Vulnerability Title
OpenClaw < 2026.2.24 - Sandbox Bind Validation Bypass via Symlink-Parent Missing-Leaf Paths
Source: NVD (National Vulnerability Database)
Vulnerability Description
OpenClaw versions prior to 2026.2.24 contain a sandbox bind validation vulnerability allowing attackers to bypass allowed-root and blocked-path checks via symlinked parent directories with non-existent leaf paths. Attackers can craft bind source paths that appear within allowed roots but resolve outside sandbox boundaries once missing leaf components are created, weakening bind-source isolation enforcement.
