CVE-2025-27823
Medium
Description
An issue was discovered in the Mail Disguise module before 1.x-1.0.5 for Backdrop CMS. It enables a 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.
