Advisory ID: 
BACKDROP-SA-CONTRIB-2025-009
Security risk: 
Moderately Critical
Vulnerability: 
Cross Site Scripting
Versions affected: 
  • SpamSpan module versions < 1.3.2
Description: 

This module enables your site to obfuscate Email addresses and prevent spambots to collect them.

The module doesn't sanitize HTML data attributes when an email address link is transformed to separate span HTML elements and then transformed back by JavaScript leading to a Cross Site Scripting (XSS) vulnerability.

This is mitigated by the fact an attacker must be able to insert span HTML elements with data attributes in the page.

See https://www.drupal.org/sa-contrib-2025-016.

A CVE has been requested, and this page will be updated as soon as an official number has been issued.

Solution: 

Upgrade your site to the most recent version of SpamSpan.
