CVE-2025-31696Network attack vector

Stored XSS via unsanitized Link field attributes

Published Mar 31, 2025 · Updated Apr 29, 2025

Stored XSS in Drupal RapiDoc OAS Field Formatter before 1.0.1 allows attackers to execute script in a viewer's browser via Link attributes. The module's overridden LinkFormatter::buildUrl() retains insufficient handling of user-controlled link attributes instead of inheriting Drupal core's corrected implementation. Exploitation requires the ability to add specific Link field attributes, typically through edit-capable web services or another module, and a victim who views the rendered field.
