Detailsinfo

A vulnerability, which was classified as critical, has been found in OpenClaw up to 2026.2.23. Affected by this issue is an unknown function. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is integrity, and availability. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability is handled as CVE-2026-27523 since 02/19/2026. The exploitation is known to be easy. Local access is required to approach this attack. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1006 by the MITRE ATT&CK project.

Upgrading to version 2026.2.24 eliminates this vulnerability. Applying the patch b5787e4abba0dcc6baf09051099f6773c1679ec1 is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
