Lifecycle Timeline
3Description
FastGPT is an AI Agent building platform. From 4.14.0 to 4.14.5, attackers can directly access the plugin system through FastGPT/api/plugin/xxx without authentication, thereby threatening the plugin system. This may cause the plugin system to crash and the loss of plugin installation status, but it will not result in key leakage. For older versions, as there are only operation interfaces for obtaining information, the impact is almost negligible. This vulnerability is fixed in 4.14.5-fix.
Analysis
Unauthenticated access to the FastGPT plugin API endpoint (FastGPT/api/plugin/xxx) in versions 4.14.0 through 4.14.5 allows remote attackers to disrupt plugin functionality and cause loss of plugin installation state without authentication. The vulnerability affects the AI/ML platform's plugin system availability and integrity, though sensitive data such as cryptographic keys are not exposed. …
