Lifecycle Timeline
4Description
OpenClaw versions prior to 2026.3.2 contain a path-confinement bypass vulnerability in browser output handling that allows writes outside intended root directories. Attackers can exploit insufficient canonical path-boundary validation in file write operations to escape root-bound restrictions and write files to arbitrary locations.
Analysis
OpenClaw prior to version 2026.3.2 allows local users with standard privileges to write files outside designated directories through insufficient path validation in the browser output handler. An attacker can exploit this path-confinement bypass to place malicious files in arbitrary filesystem locations, potentially leading to privilege escalation or system compromise.
