PYSEC-2026-3917 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...

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...
