What it is

OpenClaw versions before 2026.8.1 contain a path traversal vulnerability in QQBot voice attachment handling where filenames are decoded twice, allowing encoded traversal segments to reappear after sanitization. Attackers can supply crafted voice attachments that write files outside the intended staging directory to other process-writable locations.
