What is CVE-2025-66022?
CVE-2025-66022 is a critical vulnerability in factionsecurity faction, published on 26 Nov 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
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.
