Summary

Duplicate Advisory: OpenClaw: OpenShell FS bridge reads pin and verify the opened file before returning bytes

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-5h3g-6xhh-rg6p. This link is maintained to preserve external references.

Original Description

OpenClaw before 2026.4.22 contains a time-of-check/time-of-use race condition in the OpenShell filesystem bridge that allows attackers to read files outside the intended mount root. Attackers can exploit symlink swaps during filesystem operations to bypass sandbox restrictions and access unauthorized file contents.
