CVE-2026-44667
HighCVSS 8.7Exploitation Probability (EPSS)
Low risk11th percentile - higher than 11% of all known CVEs
Summary
FACTION prior to 1.8.3 is vulnerable to stored cross-site scripting (XSS) via attachment filenames in remediation verification file preview flows. User-supplied filenames are persisted and rendered into HTML and attribute contexts without output encoding, allowing attacker-controlled JavaScript to execute in the browser of any user who opens the affected views.
Risk Assessment
An attacker can persistently store malicious code that executes in other users' browsers, including privileged accounts, potentially leading to session theft, data modification, or privilege escalation.
Recommendation
Upgrade FACTION to version 1.8.3 or later, which fixes this vulnerability.
Other vulnerabilities in FACTION
See all- CVE-2026-44668Critical
In FACTION prior to 1.8.3, AccessControlInterceptor unconditionally calls invocation.invoke() without checking for a valid session. Four action methods in BoilerPlateConfig perform no local session check either, allowing an unauthenticated attacker to read, overwrite, deactivate, and permanently delete any boilerplate template in the system.
- CVE-2025-66022Critical
FACTION (a PenTesting Report Generation and Collaboration Framework) before version 1.7.1 allows arbitrary code execution on the server via the extension execution path. Missing authentication on the `/portal/AppStoreDashboard` endpoint allows an unauthenticated attacker to upload a malicious extension, leading to remote code execution.
- CVE-2026-44669High
FACTION is a PenTesting Report Generation and Collaboration Framework. Prior to 1.8.3, it is vulnerable to stored XSS via attachment filenames in assessment file preview flows. User-supplied filename values are persisted and later rendered into HTML/attribute contexts without output encoding, allowing attacker-controlled JavaScript to execute in the browser of any user who views the affected page. Because the payload is stored server-side and rendered to other users, exploitation is persistent and can impact privileged accounts.
Original NVD description (English source)
FACTION is a PenTesting Report Generation and Collaboration Framework. Prior to 1.8.3, Faction is vulnerable to stored cross-site scripting (XSS) via attachment filenames in remediation verification file preview flows. User-supplied filename values are persisted and then rendered into HTML and attribute contexts without output encoding, allowing attacker-controlled JavaScript to execute in the browser of any user who opens the affected verification/remediation views. Because the payload is stored server-side and rendered to other users, exploitation is persistent and can impact privileged accounts. This vulnerability is fixed in 1.8.3.
