Detailsinfo

A vulnerability was found in NUWCDIVNPT stig-manager up to 1.6.7. It has been classified as problematic. This affects an unknown code of the file src/init.js. The manipulation of the argument error/error_description with an unknown input leads to a cross site scripting vulnerability. CWE is classifying the issue as CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. This is going to have an impact on integrity. The summary by CVE is:

STIG Manager is an API and web client for managing Security Technical Implementation Guides (STIG) assessments of Information Systems. Versions 1.5.10 through 1.6.7 have a reflected Cross-Site Scripting (XSS) vulnerability in the OIDC authentication error handling code in `src/init.js` and `public/reauth.html`. During the OIDC redirect flow, the `error` and `error_description` query parameters returned by the OIDC provider are written directly to the DOM via `innerHTML` without HTML escaping. An attacker who can craft a malicious redirect URL and convince a user to follow it can execute arbitrary JavaScript in the application's origin context. The vulnerability is most severe when the targeted user has an active STIG Manager session running in another browser tab — injected code executes in the same origin and can communicate with the SharedWorker managing the active access token, enabling authenticated API requests on behalf of the victim including reading and modifying collection data. The vulnerability is patched in version 1.6.8. There is no workaround short of upgrading. Deployments behind a web application firewall that filters reflected XSS payloads in query parameters may have partial mitigation, but this is not a substitute for patching.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-41200 since 04/18/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1059.007 for this issue.

Upgrading to version 1.6.8 eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at EUVD (EUVD-2026-25158). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
