CVE-2026-41355
OpenClaw before 2026.3.28 contains an arbitrary code execution vulnerability in mirror mode that converts untrusted sandbox files into workspace hooks.
Does this matter?
Lower severity and a low EPSS score (0.12%). Track it; it rarely justifies an emergency change on its own.
Description
OpenClaw before 2026.3.28 contains an arbitrary code execution vulnerability in mirror mode that converts untrusted sandbox files into workspace hooks. Attackers with mirror mode access can execute arbitrary code on the host during gateway startup by exploiting enabled workspace hooks.
