CVE-2026-41397
OpenClaw before 2026.3.31 contains a sandbox escape vulnerability allowing attackers to traverse directory boundaries through symlink exploitation during file synchronization operations.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.47%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
OpenClaw before 2026.3.31 contains a sandbox escape vulnerability allowing attackers to traverse directory boundaries through symlink exploitation during file synchronization operations. Remote attackers can bypass sandbox restrictions by crafting malicious symlinks in mirror sync operations to access arbitrary files outside intended boundaries.
