Vulnerability Title
OpenClaw before 2026.8.1 Path Traversal via Structured Attachments
Source: CVE Program / CVE List V5
Vulnerability Description
OpenClaw versions before 2026.8.1 fail to validate all source fields in structured message attachments, allowing attackers to hide unvalidated host paths behind allowed attachment sources. Attackers can exploit this by providing multiple source fields to bypass sandbox path validation and cause Telegram delivery to read and send known host files that would otherwise be rejected.
