Pillow: Argument Injection in Ghostscript call, potentially leading into RCE
影響: pip:Pillow >= 2.6.0, < 13.0.0 → 13.0.0 Summary PIL.EpsImagePlugin.Ghostscript() builds the Ghostscript command line using the input file path (fp.name) without sanitization, placing it at -f . A filename beginning with - is interpreted by Ghostscript as an option, giving command-line argument injection; chainable to RCE (see Impact). Reproduces with Pillow's default invocation (with -dSAFER enabled). Details _Give all details on the vulnerability. Pointing to the incriminated source code is very helpful for the maintainer._ Type CWE…

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->…
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…

Mercury: Unauthenticated Remote Code Execution in /api/terminals - access control bypass
影響: pip:mercury >= 3.0.0, <= 3.2.3 → 3.2.4 Summary 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(?:/…
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…

LMCache: Remote code execution via unsafe deserialization in multiprocess mode transport
影響: pip:lmcache >= 0.3.9, < 0.5.6 → 0.5.6 Summary 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…
