CVE-2026-110228

EUVD-2026-99012
wallabag 2.6.13 through 2.6.14 contains a stored cross-site scripting vulnerability that allows authenticated users to host arbitrary HTML by triggering a failed Pocket HTML, Pocket CSV or Shaarli import. Attackers can upload an HTML file with script but no anchor elements, leaving it at the predictable /uploads/import/<user-id>.html path to execute script in victims' wallabag sessions.
