Omnigent: Uploaded Agent Bundle Allows Authenticated Runner RCE via Python Callable Tools

SummaryAn authenticated user can upload a crafted agent bundle that defines a server-side Python callable tool. The server validates the uploaded bundle, but it does not block dangerous callable: paths in untrusted user-provided agent configs.When the tool is invoked, the runner imports and...

aiosmtplib: STARTTLS response injection

ImpactWhen a connection is upgraded with STARTTLS, aiosmtplib reads the server's 220 go-ahead reply and immediately performs the TLS handshake without discarding any data still sitting in the receive buffer.

Trestle has Server-Side Template Injection (SSTI) via Recursive Template Re-evaluation of Untrusted Data

ImpactA Server-Side Template Injection SSTI vulnerability exists in multiple locations of trestle's Jinja2 rendering pipeline due to a systemic pattern: untrusted data is re-parsed as Jinja2 template source code without sandboxing. This advisory tracks the root cause across all affected code...

senaite.core Vulnerable to Eval Injection and Missing Authorization

SummaryAn unauthenticated remote code execution vulnerability in the SENAITE JSON API allows any network-reachable attacker to execute arbitrary Python on the Zope worker process via a two-request anonymous chain. The /@@API/update route is reachable to anonymous callers and runs eval on...

PYSEC-2026-3812 Chainlit has command injection via MCP stdio transport that allows unauthenticated remote code execution

Am I affected? Only if your deployment sets features.mcp.enabled = true in .chainlit/config.toml. MCP has been disabled by default since v2.7.0, so most Chainlit deployments are not affected. No authentication is required: /mcp is reachable by any client that can open a session. Summary When MCP ...

reachy_mini Allows Unrestricted Upload of File with Dangerous Type

SummaryThe Reachy Mini daemon exposes the “/api/media/sounds/upload” endpoint without authentication and file validation mechanisms. An attacker can use this endpoint to upload malicious files into the file system that will propagate in future attacks. Compromise Chain: Unauthenticated to Full Ro...

qwed-mcp has Unsafe SymPy `parse_expr()` Remote Code Execution via Unsanitized Math Expression Input

Summaryverifymathexpression in qwed-mcp v0.2.0 passes attacker-controlled strings directly to SymPy's parseexpr without restricting globaldict or validating the expression's AST. Because parseexpr internally calls eval and Python automatically injects the current module's builtins when no explici...

PraisonAI: Authentication fail-open in Recipe server allows unauthenticated access when API key or JWT auth is configured without a secret
