GHSA-82g8-464f-2mv7
No affected components available
Summary
applySkillConfigEnvOverrides previously copied skills.entries.*.env values into the host process.env without applying the host env safety policy.
Impact
In affected versions, dangerous process-level variables such as NODE_OPTIONS could be injected when unset, which can influence runtime/child-process behavior.
Required attacker capability
An attacker must be able to modify OpenClaw local state/config (for example ~/.openclaw/openclaw.json) to set skills.entries.<skill>.env or related skill config values.
Remediation
Fixed in 2026.2.21 by sanitizing skill env overrides and blocking dangerous host env keys (including NODE_OPTIONS) before applying overrides, with regression tests covering blocked dangerous keys.
