Low risk29th percentile - higher than 29% of all known CVEs
Summary
In AstrBot up to 4.23.5, the post_file function in astrbot/dashboard/routes/chat.py (File Upload Handler component) is vulnerable to path traversal via manipulation of the filename argument. The attack can be launched remotely and the exploit is publicly available. Upgrading to version 4.23.6 is recommended.
Risk Assessment
A remote attacker can exploit path traversal to read or write files outside the intended directory, potentially leading to data disclosure or code execution. The public availability of the exploit increases the risk of rapid exploitation.
Recommendation
Upgrade AstrBot to version 4.23.6 (patch aaec41e5054569ceaa1113593a34da7568e2d211). Until then, restrict access to the file upload endpoint.
