Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A flaw has been found in zhayujie chatgpt-on-wechat CowAgent up to 2.0.4. This affects the function dispatch of the file agent/memory/service.py of the component API Memory Content Endpoint. This manipulation of the argument filename causes path traversal. The attack can be initiated remotely. The exploit has been published and may be used. Upgrading to version 2.0.5 mitigates this issue. Patch name: 174ee0cafc9e8e9d97a23c305418251485b8aa89. It is recommended to upgrade the affected component. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.

dbcve analysis
How this class of weakness works · CWE-22

A file path is built from user input without being confined, so sequences like “../” let an attacker step outside the intended directory. That can expose configuration, credentials, or source code, and in the worst case lets an attacker write files where they shouldn't. A durable fix resolves and canonicalises the path, then rejects anything that escapes a known-safe base directory.
