CVE-2022-4495Network attack vector

Browser script execution via unescaped column content

Published Dec 14, 2022 · Updated Aug 3, 2024

Cross-site scripting in collective.dms.basecontent 1.0 through 1.6 allows remote authenticated users to execute script through table listings. The renderCell paths in column.py insert user full names, group titles, and content titles into generated table markup without HTML escaping. Exploitation requires attacker-controlled metadata and a user to view the affected listing, causing injected JavaScript to run in that user's browser.
