- Mail Disguise module, all versions prior to 1.x-1.0.5
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.
A CVE has been requested, and this page will be updated as soon as an official number has been issued.
Upgrade to the most recent version of the Mail Disguise module. Download available on the Mail Disguise module page.
