CVE-2026-41397
OpenClaw < 2026.3.31 - Sandbox Escape via Unrestricted File Sync and Symlink Traversal
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.
