GHSA-FFG3-P8FM-MJX2 RestrictedPython guard hooks can be shadowed via positional-only arguments

Impact RestrictedPython rewrites sensitive operations to go through guard hooks. Attribute access becomes getattrobj, name, item access becomes getitemobj, key, writes go through write, and print goes through print. The embedding application supplies these hooks to enforce its policy. Argument-na...

GHSA-XM98-3VCF-FPH7 mcp-contextforge-gateway has RestrictedPython sandbox bypass via getattr builtin in python_sandbox_server

Commit: f855e54d5b7bc1c91b977574a03b91eff6b86bb6 Component: mcp-servers/python/pythonsandboxserver/src/pythonsandboxserver/serverfastmcp.py Vulnerability RestrictedPython's sandbox in ContextForge's pythonsandboxserver sub-project allows arbitrary Python execution via three compounding weaknesses...

Plone RestrictedPython < 5.3 / 6.x < 6.1 RCE

The version of RestrictedPython installed on the remote host is prior to 5.3, or 6.x prior to 6.1. It is, therefore, affected by a remote code execution vulnerability due to not checking access to stack frames and their attributes. An authenticated, remote attacker can exploit this to bypass...

PYSEC-2026-2601 LiteLLM has a sandbox escape in custom-code guardrail

Impact The POST /guardrails/testcustomcode endpoint runs user-supplied Python inside a hand-rolled sandbox. The sandbox can be escaped using bytecode-level techniques, allowing arbitrary code execution in the proxy process — which runs as root in the default Docker image. Reaching the endpoint...
