CVE-2022-42486Network attack vector

Administrator-browser script execution via stored user-group input

Published Dec 7, 2022 · Updated Apr 23, 2025

Stored XSS in baserCMS user-group management before 4.7.2 allows remote authenticated users to execute script in an administrator's browser. The vendor identifies user-group management as the storage and rendering locus but has not published the affected field or faulty neutralization operation. Administrative privileges are required to store the payload, and a user must later open the affected administrative page; execution can alter page content or expose cookies.
