CVE-2026-27523

OpenClaw < 2026.2.24 - Sandbox Bind Validation Bypass via Symlink-Parent Missing-Leaf Paths

State: Published
Severity: 6.9 Medium
Published: Mar 18, 2026
Updated: Jun 23, 2026
Reserved: Feb 19, 2026

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.
