Path Traversal in OpenClaw QQBot Voice Handling

Publication date: 2026-09-26

Last updated on: 2026-09-26

Assigner: VulnCheck

Description
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.

Executive Summary

CVE-2026-100549 is a path traversal vulnerability in OpenClaw versions before 2026.8.1 affecting the QQBot voice attachment handling. Filenames are decoded twice, allowing encoded path traversal sequences to bypass sanitization and escape the intended staging directory.

Detection Guidance

Check for unexpected files in writable system directories outside the intended voice staging folder. Review QQBot logs for voice attachment processing errors or unusual file paths. Look for files with encoded traversal sequences in filenames (e.g., %2e%2e%2f or ..%2f).

Commands: grep -r "..%2f" /var/log/qqbot/ 2>/dev/null; find / -type f -name "*%2e%2e%2f*" 2>/dev/null; ls -la /tmp/ | grep -i voice

Impact Analysis

Attackers can exploit this to write files outside the designated voice staging directory to other writable system locations. This could lead to unauthorized file creation, data corruption, or disruption of services relying on those directories.

Compliance Impact

This vulnerability could potentially impact compliance with GDPR and HIPAA by allowing unauthorized file writes outside intended directories. For GDPR, it may risk unauthorized data access or modification affecting personal data integrity. For HIPAA, it could compromise protected health information integrity or availability if files are written to unintended locations.

Mitigation Strategies

Upgrade OpenClaw to version 2026.8.1 or later immediately. Disable QQBot voice forwarding for untrusted senders. Remove any unexpected staged media files in voice directories. Monitor system for unauthorized file writes.
