CVE-2026-41336

OpenClaw before 2026.3.31 allows workspace .env files to override the OPENCLAW_BUNDLED_HOOKS_DIR environment variable, enabling loading of attacker-controlled hook code. Attackers can replace trusted default-on bundled hooks from untrusted workspaces to execute arbitrary code.

Análisis

OpenClaw is a niche open-source project, and while this vulnerability allows for arbitrary code execution via malicious workspace environment files, it is not a common tool in the standard web, mobile, or backend development stack. It does not warrant a community-wide alert as the impact is limited to a very small user base.
