Project: SpamSpan filter [1]
Date: 2025-February-12
Security risk: *Moderately critical* 13 ∕ 25
AC:Complex/A:User/CI:Some/II:Some/E:Theoretical/TD:All [2]
Vulnerability: Cross Site Scripting

Affected versions: <3.2.1
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.

Solution: 
Install the latest version:

  * If you use the Spamspan filter module for Drupal 10.x, upgrade to Spamspan
    filter 3.2.1 [3]
