pypdf: Possible infinite loop when hitting EOF in standard xref table
影響: pip:pypdf < 6.20.0 → 6.20.0 An attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires an incomplete file which ends inside the xref table. Patches This has been fixed in [pypdf==6.20.0](https://github.com/py-pdf/pypdf/releases/tag/6.20.0). Workarounds If you cannot upgrade yet, consider applying the changes from PR [#4170](https://github.com/py-pdf/pypdf/pull/4170). Notes This has been reported through both the secure channel and as a public issue at [#4169](https://gith…
virtualenv bash activate runs commands from an environment name with a backslash before $
影響: pip:virtualenv <= 21.14.6 → 21.14.7 The bash activate script escapes the environment name for only one of the two passes bash makes over PS1, so a backslash in the name undoes the escaping and a name containing \$(...) runs as commands in the user's shell each time bash draws the prompt. Affected area src/virtualenv/activation/bash/activate.sh, the block that prepends the environment name to PS1. Attacker-controlled input The environment name: the environment directory's name, or the --prompt or VIRTUALENV_PROMPT value. A…
pypdf: Possible large memory usage for streams with multiple filters
影響: pip:pypdf < 6.20.0 → 6.20.0 An attacker who uses this vulnerability can craft a PDF which leads to large memory consumption. This requires accessing any stream with a large amount of filters or multiple filters which pass around large amounts of data. Patches This has been fixed in [pypdf==6.20.0](https://github.com/py-pdf/pypdf/releases/tag/6.20.0). Workarounds If you cannot upgrade yet, consider applying the changes from PR [#4173](https://github.com/py-pdf/pypdf/pull/4173).
virtualenv activate runs commands from the environment name in zsh with PROMPT_SUBST
影響: pip:virtualenv <= 21.14.3 → 21.14.4 zsh users activate an environment with the bash activate script, which puts the environment name into PS1. Since 21.13.0 the script escapes backslashes, dollar signs and backticks in that name, but only when BASH_VERSION is set, so zsh gets the raw value. With the PROMPT_SUBST option set, zsh runs parameter expansion, command substitution and arithmetic expansion on PS1 each time it draws the prompt. A name that contains $(...), backticks or ${...} then runs as commands in the user's she…
virtualenv activate.fish runs commands from a path or prompt with a backslash before a quote
影響: pip:virtualenv <= 21.14.1 → 21.14.2 FishActivator defines no quote(), so it inherits ViaTemplateActivator.quote, which returns shlex.quote(string). That function follows POSIX sh rules, where a backslash inside single quotes stays a literal character. fish reads \' inside single quotes as an escaped quote and \\ as an escaped backslash. A value with a backslash before a quote therefore ends the literal somewhere other than where shlex.quote put the end, and fish expands the command substitution that follows. The environmen…
virtualenv activation scripts run code from a path that contains a placeholder name
影響: pip:virtualenv >= 20.26.6, <= 21.14.1 → 21.14.2 ViaTemplateActivator.instantiate_template replaces the placeholders in an activation template one key at a time, each across the whole text. When a value that it already substituted and quoted contains the name of a later placeholder, the later pass rewrites that name inside the quoted literal. The inserted value brings its own quotes, which close the outer literal, and the rest of the path runs as code when a user activates the environment. __VIRTUAL_NAME__ holds the environment's direc…

Pillow: Out-of-bounds access in _imagingmorph on a zero-width image
影響: pip:Pillow <= 12.3.0 → 13.0.0 A PPM or PGM file can declare a width of 0, which Pillow accepts, producing an image of size (0, N). Passing that image to ImageMorph.MorphOp.apply() makes the native morphology code index a row buffer at outrow[width - 1], which is outrow[-1] when the width is 0. The process crashes. Details The PPM parser reads width and height with no lower-bound check: - src/PIL/PpmImagePlugin.py:119 The native apply() writes the row edges with no guard that the width is positive: - src/_imagingmorp…
Pillow: GIF seek keeps rejected size after DecompressionBombError, allowing DoS
影響: pip:Pillow >= 9.2.0, < 13.0.0 → 13.0.0 ============================================================================ GIF seek keeps rejected size after DecompressionBombError, allowing DoS Location: src/PIL/GifImagePlugin.py:293 in GifImageFile._seek() Commit: a707c6b21c313880d0771e54965d142dd42358b6 ============================================================================ A GIF of about 60 bytes can make Pillow allocate gigabytes of memory. This affects applications that catch the "image too large" error raised while stepping to…
Pillow: EPS load(scale) lets Ghostscript render past the decompression bomb limit
影響: pip:Pillow >= 2.3.0, <= 12.3.0 → 13.0.0 ============================================================================ EPS load(scale) lets Ghostscript render past the decompression bomb limit Location: src/PIL/EpsImagePlugin.py:92 in Ghostscript() Commit: a707c6b21c313880d0771e54965d142dd42358b6 ============================================================================ When an application opens an untrusted Encapsulated PostScript file and asks Pillow to render it at a larger scale, Pillow has Ghostscript produce an image several ti…
Pillow: TiffDecode returns uninitialized memory as pixels for short JPEG strips
影響: pip:Pillow >= 5.3.0, < 13.0.0 → 13.0.0 ============================================================================ TiffDecode returns uninitialized memory as pixels for short JPEG strips Location: src/libImaging/TiffDecode.c:554 in _decodeStrip() Commit: a707c6b21c313880d0771e54965d142dd42358b6 ============================================================================ Pillow hands back leftover process memory as image pixels when it opens a small crafted TIFF file. Anyone who can get an application to open their image, and can se…
Pillow: TIFF encoder ColorMap plane-size mismatch causes a heap out-of-bounds read
影響: pip:Pillow <= 12.3.0 → 13.0.0 A small attacker-supplied TIFF can be opened and loaded normally, then reach an out-of-bounds read when an application saves it back to TIFF with retained metadata. The fixed reproducer is a 1×1, 16-bit grayscale, PackBits-compressed TIFF containing tag 320 (ColorMap) with 768 SHORT values: three zero-filled planes of 256 entries each. No Python object is forged and no metadata is injected after loading. Pillow's TIFF encoder allocates 768 × 2 = 1536 bytes, then passes three plane point…
Pillow: Unbounded recursion parsing a PDF page tree or trailer chain (incomplete fix for CVE-2026-42310)
影響: pip:pillow >= 5.1.0, < 13.0.0 → 13.0.0 When an application appends to an existing PDF with Image.save(..., format="PDF", append=True), Pillow parses that file with PdfParser. Two recursive parsers have no effective bound. linearize_page_tree follows /Kids with no visited set or depth limit, so a cyclic or duplicated page tree recurses without end. read_prev_trailer rejects only an exactly repeated /Prev offset, so a long chain of unique offsets still recurses. The trailer-loop guard added for CVE-2026-42310 does not cover ei…
Pillow tiled-TIFF decoder reads past tile buffer in copy4 (Unpack.c:1290)
影響: pip:pillow >= 8.2.0, < 13.0.0 → 13.0.0 Pillow's libImaging _decodeTile decoder, used to decode tiled TIFF images, allocates a per-tile buffer using realloc(state->buffer, TIFFTileSize(tiff)). After each TIFFReadTile it then iterates tile_y from 0 up to current_tile_length and calls the configured row unpacker (here copy4) with the source pointer state->buffer + tile_y row_byte_size. When libtiff returns a tile_bytes_size smaller than the worst-case row_byte_size tile_length, the inner stride-and-copy loop walks past the real…
Pillow: OOB read in TiffDecode.c tile and RGBA paths leaks heap memory into pixels
影響: pip:Pillow >= 8.1.0, < 13.0.0 → 13.0.0 ============================================================================ OOB read in TiffDecode.c tile and RGBA paths leaks heap memory into pixels Location: src/libImaging/TiffDecode.c:483 in _decodeTile() Commit: a707c6b21c313880d0771e54965d142dd42358b6 ============================================================================ Pillow reads past the end of a heap buffer when decoding certain malformed compressed TIFF files, and copies the bytes it reads into the pixels of the image it re…
Pillow: Heap buffer overflow in ImagingJpegDecode
影響: pip:Pillow <= 12.3.0 → 13.0.0 JpegImageFile.draft() — which Image.thumbnail() calls automatically — requests 1/2, 1/4 or 1/8 scaled JPEG output and shrinks self._size and the tile extents to match, so _setimage() allocates a single-row decode buffer of ceil(W/s) samples. ImagingJpegDecode() sets cinfo.scale_num/scale_denom, calls jpeg_start_decompress(), and then reads scanlines into that buffer without ever comparing cinfo.output_width, cinfo.output_height or cinfo.out_color_components against state->xsize, state->…
AIOHTTP: Absolute-form request targets can spoof Request.scheme
影響: pip:aiohttp <= 3.14.3 → 3.14.4 An attacker sending an absolute-form request can spoof the scheme used. Impact If user code depends on the Request.scheme attribute for anything security related, an attacker may be able to circumvent this logic, tricking the application into thinking a connection is encrypted when it is not, or vice versa. Workaround A WAF rule to reject absolute-form requests (legitimate requests should only use this form for proxies).
AIOHTTP: Connector pool exhaustion via Max-Age overflow
影響: pip:aiohttp <= 3.14.3 → 3.14.4 An overflow in Max-Age processing can skip closing a connection. Impact An attacker may be able to exhaust the connection pool temporarily, until garbage collection resolves the connections.
AIOHTTP: Pure-Python parser request smuggling
影響: pip:aiohttp <= 3.14.3 → 3.14.4 The pure Python parser is vulnerable to an HTTP request smuggling attack. Impact If users are using the Python parser (AIOHTTP_NO_EXTENSIONS, or not a standard wheel installed), then an application may be vulnerable to a request smuggling attack. Workaround Switch to the default C parser.
AIOHTTP: File descriptor exhaustion in multipart requests
影響: pip:aiohttp >= 2.0.0, < 3.14.4 → 3.14.4 An attacker can exhaust file descriptors with specially crafted multipart requests. Impact If a handler uses Request.post(), it may be possible for an attacker to use an unlimited number of file descriptors, potentially resulting in resource exhaustion.
uv's bundled CA store trusts an emSign root whose intermediate CA keys are compromised
影響: pip:uv < 0.13.4 → 0.13.4 By default, uv verifies TLS connections against a vendored copy of the webpki-root-certs bundle. Versions before 0.13.4 include the emSign ECC Root CA - G3 root. Eight eMudhra intermediate CA certificates that chain to that root have compromised private keys, and the CA has revoked them. An attacker with one of the compromised keys can issue certificates that uv accepts for any hostname, and can be used to issue certificates to enable MITM attacks. uv 0.13.4 removes the root from its vendored b…
certifi bundles emSign root CAs with compromised intermediate CA keys
影響: pip:certifi >= 2019.03.09, < 2026.10.19 → 2026.10.19 Certifi versions before 2026.10.18 include the emSign ECC Root CA - G3 root certificate in their bundled CA store. Eight eMudhra intermediate CA certificates that chain to this root have compromised private keys and the CA has revoked them. An attacker with one of the compromised keys can issue valid-looking certificates for any hostname. If the attacker is also on-path, they can intercept or modify TLS traffic from clients that trust the certifi bundle. Examples include requests, urllib3 and p…

aiohttp server lacks an initial request/header timeout
影響: pip:aiohttp <= 3.14.3 → 3.14.4 The keepalive timeout was not used during the initial portion of a request. Impact An attacker could keep an idle connection open indefinitely before sending any data. Workaround Use a reverse proxy (as recommended for all production deployments) with sensible keepalive limits.
aiohttp: Multiple instances of excessive or unbounded memory/CPU use
影響: pip:aiohttp <= 3.14.3 → 3.14.4 Multiple cases were found where aiohttp could use excessive or unbounded memory, or excessive CPU consumption on attacker controlled requests. Impact An attacker could cause resource exhaustion through specially crafted requests.
Mercury: Stored / DOM Cross-Site Scripting (XSS): mr.Markdown renders untrusted content as raw, unsanitized HTML
影響: pip:mercury >= 3.0.0, < 3.2.11 → 3.2.11 Mercury turns Jupyter notebooks into shared web apps/dashboards. The mr.Markdown widget converts its input to HTML with python-markdown and no sanitization step. MarkdownWidget is an ipywidgets.HTML widget, whose value is written to the page as raw HTML (via innerHTML) with no sanitization, so the result reaches the DOM verbatim. When an app passes untrusted data (database rows, user submissions, uploaded file contents, or an external/LLM API response) to mr.Markdown, HTML/JS in that da…
Mercury: Unauthenticated Remote Code Execution in /api/terminals - access control bypass
影響: pip:mercury >= 3.0.0, <= 3.2.3 → 3.2.4 A missing comma in mercury_app/block_handler.py's BLOCKED_PATTERNS list causes the blocklist to fail to cover the /api/terminals endpoint. As a result, any unauthenticated attacker can spawn a full, interactive OS-level shell on the host running Mercury. Details The blocklist in mercury_app/block_handler.py is defined as: BLOCKED_PATTERNS = [ # JupyterLab UI + API r"/lab(?!/(?:extensions/|api/settings(?:/|$)|api/translations(?:/|$)))(?:/.)?" r"/api/terminals(?:/.)?", r"/api/shutdown(?:/…
Graphify Fortran extractor: incomplete cpp #include hardening allows arbitrary host-file read/exfiltration when indexing an untrusted repo
影響: pip:graphifyy >= 0.7.2, < 0.9.70 → 0.9.70 The Fortran extractor's C-preprocessor step (graphify/extractors/fortran.py, _cpp_preprocess) applies an incomplete #include hardening. The -nostdinc -I /dev/null flags it relies on (comment "Security (F-007)") do not stop a capital-F Fortran source file from including absolute paths (#include "/etc/passwd") or from path-traversing out of the corpus (#include "../../../../home/victim/.ssh/id_rsa"). cpp always searches the directory of the file being preprocessed for quoted includes and…
Mercury: Unauthenticated Remote Code Execution via /api/kernels
影響: pip:mercury <= 3.2.5 → 3.2.6 Mercury runs a JupyterLab server with anonymous access by default (mercury_app/__main__.py sets --IdentityProvider.token='' when no --token/MERCURY_TOKEN is given; when tokenless it also sets --ServerApp.disable_check_xsrf=True). It relies on a blocklist (mercury_app/block_handler.py BLOCKED_PATTERNS: /lab, /api/terminals, /api/shutdown, /files) to keep anonymous users off dangerous Jupyter endpoints. The vulnerability /api/kernels is NOT in the blocklist (and cannot be — Mercury needs kernels…
LoopX serve-status permissive CORS policy exposes control-plane state and private Markdown files
影響: pip:loopx >= 0.0.1, < 0.4.5 → 0.4.5 loopx serve-status sends Access-Control-Allow-Origin: on every response, including its unauthenticated GET routes. Because the endpoint is unauthenticated and bound to a fixed, well-known loopback port, any website the operator visits can read LoopX control-plane state and the contents of Markdown files inside every registered goal repo, using a plain fetch() with no user interaction. The write endpoints are not affected — they are correctly Origin-checked. This report is strictly about…

LMCache: Remote code execution via unsafe deserialization in multiprocess mode transport
影響: pip:lmcache >= 0.3.9, < 0.5.6 → 0.5.6 LMCache is vulnerable to Unauthenticated Remote Code Execution via Pickle Deserialization on the Multiprocess ZMQ Transport Details LMCache multiprocess mode, also called distributed mode, opens an unauthenticated ZeroMQ ROUTER so worker processes can register and share KV cache blocks. The intended clients are sibling LMCache processes. There is no CURVE, ZAP, password, or message authentication on that socket. LMCache used only inside a vLLM process does not open this port. The transp…
Claude Agent SDK: Argument Injection via resume Option Allows Arbitrary Command Execution
影響: pip:claude-agent-sdk < 0.2.121 → 0.2.121 The Claude Agent SDK for Python passed the resume option to the Claude CLI without validation, allowing a value beginning with - to be interpreted as a separate CLI flag. An attacker who controlled the resume value could inject an --mcp-config flag defining a stdio MCP server, resulting in arbitrary command execution at CLI startup that bypassed the SDK's permission controls. Exploitation required an application to pass untrusted input as the session ID to resume. Users are advised to update to…

Pipecat: Public exposure of Pipecat’s development runner can allow unauthenticated bot session creation
影響: pip:pipecat-ai >= 0.0.98, <= 1.5.0 → 1.6.0 Pipecat’s built-in development runner exposes endpoints that create bot sessions and, for the Daily transport, paid Daily rooms. These development endpoints intentionally do not authenticate callers. The runner binds to localhost by default and is designed exclusively for local development. It is not built or supported as a production server. Exploitation therefore requires an operator to deliberately make the development runner reachable from an untrusted network, such as by setting --host 0.0…
JupyterLab: Command link trust prompt in JupyterLab can trust a document other than the one clicked
影響: pip:jupyterlab >= 4.6.0, <= 4.6.3 → 4.6.4, pip:jupyterlab >= 4.5.7, <= 4.5.10 → 4.5.11, pip:notebook >= 7.5.6, <= 7.6.2 → 7.6.3, pip:jupyterlite-core >= 0.7.5, <= 0.8.3 → 0.8.4 A Markdown file or a notebook output can carry a button that runs a JupyterLab command. Since 4.5.7 the first click on such a button opens a prompt naming the command, with Cancel, Run Once and Trust. Choosing Trust runs the command and marks the document trusted, so its later buttons run without a prompt. Which document gets marked is decided when the user answers, not when they click. Both trust commands read whichever document is current at that moment: markdownviewer:trust uses…
