Advisory ID: 
BACKDROP-SA-CONTRIB-2025-007
Security risk: 
Moderately Critical
Vulnerability: 
Cross Site Scripting
CVE ID: 
CVE-2025-27823
Versions affected: 
  • Mail Disguise module, all versions prior to 1.x-1.0.5
Description: 

The Mail Disguise module enables a Backdrop website to obfuscate email addresses, and should prevent spambots from collecting them. The module doesn't sufficiently validate the data attribute value on links, potentially leading to a Cross Site Scripting (XSS) vulnerability.

This is mitigated by the fact an attacker must be able to insert link (<a>) HTML elements containing data attributes into the page.

Solution: 

Upgrade to the most recent version of the Mail Disguise module. Download available on the Mail Disguise module page.
