CVE-2025-3733Network attack vector

Cross-site scripting via unsanitized image alt text

Published Apr 16, 2025 · Updated Apr 16, 2025

Cross-site scripting in Drupal baguetteBox.js before 2.0.4 and 3.0.0 allows remote attackers to execute script through crafted image alt text. The image-field formatter places user-supplied alt text into gallery output without sufficient sanitization, allowing browser interpretation as active markup. Exploitation requires attacker-controlled alt text to reach a rendered gallery; execution occurs under the affected site's browser origin.
