FKIE_CVE-2026-32988

Vulnerability from fkie_nvd - Published: 2026-03-31 12:16 - Updated: 2026-07-25 10:10
Severity
7.5 (High) - CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:N/I:H/A:H
Summary
OpenClaw before 2026.3.11 contains a sandbox boundary bypass vulnerability in fs-bridge staged writes where temporary file creation and population are not pinned to a verified parent directory. Attackers can exploit a race condition in parent-path alias changes to write attacker-controlled bytes outside the intended validated path before the final guarded replace step executes.
