CVE-2026-7396 Details
Description
A vulnerability was identified in NousResearch hermes-agent 0.8.0. Affected by this issue is some unknown functionality of the file gateway/platforms/wecom.py of the component WeChat Work Platform Adapter. The manipulation leads to path traversal. It is possible to initiate the attack remotely. The exploit is publicly available and might be used.
A path traversal vulnerability has been identified in the WeCom (WeChat Work) platform adapter of NousResearch hermes-agent version 0.8.0. The issue arises because the adapter processes 'file://' URLs for media attachments without proper validation of the file path, allowing remote attackers to read arbitrary files from the server's filesystem. This includes sensitive files such as configuration files, SSH keys, and API credentials. The vulnerability is exploitable through the WeCom messaging platform, where an attacker can send a message that triggers the reading of a file via a 'file://' URL.
The vulnerability has been fixed in version 0.8.1. Users should update to this version.
