CVE-2025-9550Network attack vector

Facet-administrator XSS via insufficiently filtered text

Published Oct 10, 2025 · Updated Oct 10, 2025

Cross-site scripting in Drupal Facets before 2.0.10 and 3.0.0 allows remote authenticated users to execute script via crafted facet text. The module places certain facet-administrator-supplied text into generated pages without sufficient filtering; Drupal has not disclosed the specific field or render path. The attacker needs the administer facets permission, and a viewer must load the affected page for script to run in that viewer's browser context.
