This patch is called 8c9f35cdb51692b650ddf05b259ccdd75cc9a83c. It is recommended to upgrade the affected component.
AnalysisAI
Code injection in OpenClaw 2026.2.19 and earlier through the Skill Env Handler's applySkillConfigenvOverrides function allows authenticated remote attackers to execute arbitrary code with low integrity and confidentiality impact. An authenticated user can manipulate environment configuration settings to inject malicious code that executes in the context of the application. Mitigation requires upgrading to version 2026.2.21-beta.1 or later, as no official patch is currently available for production releases.
