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. For more information, please see: "CVE-2025-55449-AstrBot-RCE" (https://github.com/Marven11/CVE-2025-55449-AstrBot-RCE)
