35th percentile - higher than 35% of all known CVEs

Summary

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.

Risk Assessment

Risk of unauthorized reading and sending of host files via Telegram, potentially leading to sensitive data disclosure.

Recommendation

Update OpenClaw to version 2026.8.1 or later to ensure full validation of all source fields in attachments.
