NVD 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.
What to do
- Upgrade OpenClaw to
2026.4.2or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
