A code injection vulnerability has been identified in OpenClaw version 2026.2.19-2. The issue arises in the 'applySkillConfigEnvOverrides' function within the Skill Environment Handler component. This vulnerability allows for the injection of harmful code by manipulating environment variables related to skills, which can then be executed in the application's runtime. The vulnerability can be exploited remotely, but requires access to modify OpenClaw's local configuration.
Users are advised to upgrade to OpenClaw version 2026.2.21-beta.1, which addresses this vulnerability by sanitizing skill environment overrides and blocking the injection of harmful host environment keys, including 'NODE_OPTIONS'.
