AstrBotDevs AstrBot 3.5.15 has Advanced_System_for_Text_Response_and_Bot_Operations_Tool as the hardcoded private key used to sign a JWT.
Impact
### Summary AstrBot uses a hard-coded JWT signing key, allowing attackers to execute arbitrary commands by installing a malicious plugin. ### Details AstrBot uses a [hard-coded JWT signing key](https://github.com/AstrBotDevs/AstrBot/blob/v3.5.16/astrbot/core/__init__.py), which allows attackers to bypass the authentication mechanism. Once bypassed, the attacker can install a Python plugin that will be imported [here](https://github.com/AstrBotDevs/AstrBot/blob/master/astrbot/dashboard/routes/plugin.py), enabling arbitrary command execution on the target host. ### Impact All publicly accessible AstrBot instances are vulnerable.
