CVE-2025-66022FACTION Unauthenticated Custom Extension Upload leads to RCE
Critical 9.7

A critical-severity improper authentication in faction from factionsecurity. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.7% (higher than 54% of all known vulnerabilities).
Official description
FACTION is a PenTesting Report Generation and Collaboration Framework. Prior to version 1.7.1, an extension execution path in Faction’s extension framework permits untrusted extension code to execute arbitrary system commands on the server when a lifecycle hook is invoked, resulting in remote code execution (RCE) on the host running Faction. Due to a missing authentication check on the /portal/AppStoreDashboard endpoint, an attacker can access the extension management UI and upload a malicious extension without any authentication, making this vulnerability exploitable by unauthenticated users. This issue has been patched in version 1.7.1.
