Headline
GHSA-4m32-cjv7-f425: AstrBot is vulnerable to RCE with hard-coded JWT signing keys
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, which allows attackers to bypass the authentication mechanism. Once bypassed, the attacker can install a Python plugin that will be imported here, 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
Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
