ApostropheCMS: Unauthenticated resource exhaustion via pre-auth aposBigUpload processing in @apostrophecms/import-export
影響: npm:apostrophe < 4.33.0 → 4.33.0, npm:@apostrophecms/import-export < 3.7.0 → 3.7.0 Summary A potential unauthenticated denial-of-service vulnerability exists in the chunked import upload path used by @apostrophecms/import-export. The affected import API routes invoke: self.apos.http.bigUploadMiddleware() before the actual import handler performs its authentication check. Because no authorize callback is supplied to bigUploadMiddleware(), unauthenticated requests can reach the aposBigUpload start, chunk, and end operations before the later req.user check rejects the import. As…

Cachet has Stored XSS in Incident Component
影響: composer:cachethq/cachet <= 2.4.1 Summary A stored Cross-Site Scripting (XSS) vulnerability exists in the incident creation form, allowing an authenticated attacker to inject malicious HTML/JavaScript that executes in the browser of any user who views the status page, potentially leading to session token theft and account takeover. Details The incident Name and Message fields do not properly sanitize HTML event handler attributes. While tags appear to be filtered, event-based payloads are not blocked. Affected endpoint: /dashbo…
A2A Java SDK: Push notification credentials logged in cleartext on protobuf parse failure
影響: maven:org.a2aproject.sdk:a2a-java-sdk-transport-rest < 1.3.0.Final → 1.3.0.Final Impact. Push notification bearer tokens and authentication credentials submitted by clients are written to server log files in cleartext. Any operator, log aggregation system, or attacker with log access can read these secrets and use them to authenticate to the client's push notification endpoints, potentially sending forged task status updates. Where. transport/rest/src/main/java/org/a2aproject/sdk/transport/rest/handler/RestHandler.java:676 in parseRequestBody What. The parseRequestBody meth…
A2A Java SDK: Android synchronous POST forwards credentials across authorities after incomplete redirect fix
影響: maven:org.a2aproject.sdk:a2a-java-sdk-http-client-android >= 1.3.0.Final, <= 1.3.1.Final → 1.3.2.Final The GHSA-9rhm fix added this safe setting in AndroidA2AHttpClient.createConnection(): connection.setInstanceFollowRedirects(false); The synchronous POST builder later overwrites it: private boolean followRedirects = true; public A2AHttpResponse post() throws IOException { HttpURLConnection connection = createConnection("POST", false); connection.setInstanceFollowRedirects(followRedirects); // ... } The second assignment wins. JSONRPCTransport and RestTransport both add interceptor-produced head…
A2A Java SDK has Server-Side Request Forgery (SSRF) in push-notification delivery
影響: maven:org.a2aproject.sdk:a2a-java-sdk-server-common < 1.3.0.Final → 1.3.0.Final --- - Ecosystem: Maven - Affected package: org.a2aproject.sdk:a2a-java-sdk-server-common (push-notification delivery) - Affected versions: /latest/meta-data/iam/security-credentials/. Use returnImmediately: true, header A2A-Version: 1.0, and role ROLE_USER. The URL is stored verbatim. (Equivalent via CreateTaskPushNotificationConfig on an existing task.) 3. As the task emits state/artifact updates, the sender POSTs each one to the stored URL, from the server's own network position: POST /latest…
A2A Java SDK has a fail-open default task authorization
影響: maven:org.a2aproject.sdk:a2a-java-sdk-server-common < 1.3.0.Final → 1.3.0.Final Draft text for GHSA-qw47-mcm5-934w. The body below drops into the GitHub advisory description field; the metadata block maps to the form fields. Set the patched version at release; publish when the fix ships._ --- - Ecosystem: Maven - Affected package: org.a2aproject.sdk:a2a-java-sdk-server-common (task store / authorization) - Affected versions: <= 1.2.0.Final (and 1.2.1.Final-SNAPSHOT on main prior to the fix) - Patched version: _(the release that carries the fix, e.g. 1.2.1.Final)_ - CWE: CW…
A2A Java SDK send client credentials under server-controlled HTTP header name, enabling leakage via redirect
影響: maven:org.a2aproject.sdk:a2a-java-sdk-parent < 1.3.0.Final → 1.3.0.Final Impact. A malicious or compromised A2A agent can cause the client's API key credential to be forwarded to an arbitrary third-party server. The agent serves an AgentCard with an APIKeySecurityScheme specifying a custom header name, then responds with an HTTP redirect. The JDK HttpClient follows the redirect and forwards the custom header containing the credential, since only the standard Authorization header may be stripped on cross-origin redirects. Where. client/transport/spi/src/main/java/org…
Pillow: Out-of-bounds access in _imagingmorph on a zero-width image
影響: pip:Pillow <= 12.3.0 → 13.0.0 Summary 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 Summary 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 Summary 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 Summary 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 Summary 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->…
@angular/common: XSRF Token Leakage via URL Parsing Discrepancy in Angular HTTP Client (Incomplete fix for CVE-2025-66035)
影響: npm:@angular/common >= 21.0.0, < 21.0.3 → 21.0.3, npm:@angular/common >= 20.0.0, < 20.3.34 → 20.3.34, npm:@angular/common <= 19.2.25 An incomplete fix for [GHSA-58c5-g7wp-6w37](https://github.com/angular/angular/security/advisories/GHSA-58c5-g7wp-6w37) (CVE-2025-66035) in @angular/common's HTTP Client (HttpClient) allows Cross-Site Request Forgery (XSRF) tokens to be leaked to attacker-controlled cross-origin domains when requests use URLs that exploit parsing discrepancies between regular expressions and the browser's WHATWG URL parser. Technical Description To address CVE-2025-66035, xsrfInterceptorFn introduced a regular…
markdown-it: Quadratic-time rendering of a single multi-line link reference definition with default options (regression since 14.0)
影響: npm:markdown-it >= 14.1.0, < 14.3.3 → 14.3.3, npm:markdown-it >= 15.0.0, < 15.0.3 → 15.0.3 Summary A link reference definition whose label or title is never closed is O(n²) in markdown-it 15.0.2 with default options. Continuation lines are pulled lazily with str += lineContent in src/rules_block/reference.ts, and the subsequent charCodeAt and slice calls flatten the V8 cons-string, copying everything collected so far; this runs before the rule decides the definition is invalid. It is a regression introduced by PR #1004 in 14.0.0: 13.0.2 processed a 313 KB input in 125 ms, while every…
markdown-it: Quadratic-time denial of service in inline HTML parsing with html enabled
影響: npm:markdown-it < 14.3.3 → 14.3.3, npm:markdown-it >= 15.0.0, < 15.0.3 → 15.0.3 Summary With html: true, markdown-it takes quadratic time to parse repeated unterminated HTML constructs inside a paragraph. This affects HTML comments ( , ?>, >, and ]]>. When the terminator is absent, matching fails. Parsing eventually reaches the next opener and scans an overlapping suffix again. Repeating this across the paragraph produces quadratic total work. For these inputs, the problem is repeated scanning across separate matches. The payload must reach inline parsing. Prefixing it wit…
MCP TypeScript server SDK: Shared transport or server instances delivered one HTTP client's messages to another
影響: npm:@modelcontextprotocol/server >= 2.0.0, < 2.3.0 → 2.3.0 Summary In affected versions, an MCP server reached over HTTP could deliver one client's responses and notifications to another client. This happened when clients shared one stateless transport, or one McpServer or Server instance. Messages were matched to a connection by JSON-RPC id alone. SDK clients number requests from 0, so ids collide in normal use. Am I affected? Yes, if more than one client can reach your HTTP endpoint and your code creates the transport or the server once at startup, i…
MCP TypeScript SDK: One HTTP request within the default size limit could exhaust server memory during validation
影響: npm:@modelcontextprotocol/sdk >= 1.3.0, < 1.32.0 → 1.32.0, npm:@modelcontextprotocol/server >= 2.0.0, < 2.3.0 → 2.3.0 Summary In affected versions, servers put no limit on how many array elements and object keys they validated in one request. One HTTP request within the default 4 MiB size limit could exhaust the server's memory, and the process aborted with JavaScript heap out of memory. No credentials are needed, unless you authenticate requests before they reach the SDK. Am I affected? Yes, if clients you do not fully trust can reach your server over HTTP. The risk is highest for McpServer tools whose input…
AIOHTTP: Absolute-form request targets can spoof Request.scheme
影響: pip:aiohttp <= 3.14.3 → 3.14.4 Summary 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: Cookie from subdomain can remove Host-Only Scope from existing cookies
影響: pip:aiohttp <= 3.14.3 → 3.14.4 Summary A subdomain can remove the Host-Only flag from an existing cookie to a parent domain. Impact A user accessing untrusted subdomains could see their Host-Only protections stripped from cookies. Given most usecases won't reflect these cookies to a browser, the impact is limited.
AIOHTTP: Connector pool exhaustion via Max-Age overflow
影響: pip:aiohttp <= 3.14.3 → 3.14.4 Summary 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 Summary 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 Summary 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.
