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.
