Vendor and ecosystem advisories describing this.

WID-SEC-W-2026-2181Drupal Extensions: Mehrere SchwachstellenDeutsch2026-07-01csaf · cert_bundDE
Ein entfernter, authentisierter Angreifer kann mehrere Schwachstellen in Drupal ausnutzen, um einen Cross-Site Scripting Angriff durchzuführen, Sicherheitsmaßnahmen zu umgehen und Daten zu manipulieren.
DRUPAL-CONTRIB-2026-0692026-07-01vendor · osvUS
The Colorbox module integrates with the Colorbox JavaScript library to display content in an overlay above the page. The module doesn't sufficiently protect against injection of malicious JavaScript under certain scenarios. This vulnerability is mitigated by the fact that an attacker must have a role that permits them to enter HTML content.
