CVE-2026-35650
OpenClaw < 2026.3.22 - Environment Variable Override Bypass via Inconsistent Sanitization
Description
OpenClaw before 2026.3.22 contains an environment variable override handling vulnerability that allows attackers to bypass the shared host environment policy through inconsistent sanitization paths. Attackers can supply blocked or malformed override keys that slip through inconsistent validation to execute arbitrary code with unintended environment variables.
