Summary

Duplicate Advisory: Shell positional parameters could weaken strict inline-eval checks

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-5cj2-3jr2-5h77. This link is maintained to preserve external references.

Original Description

OpenClaw before 2026.4.2 contains an inline-eval bypass vulnerability allowing authenticated operators to weaken strict allowlist checks via shell positional parameters. Attackers can combine allowlisted tools with shell positional arguments to place inline-eval content in shell carriers outside intended allowlist rules, enabling execution of unapproved shell-provided content.

Severity
