Name of the Vulnerable Software and Affected Versions Mbin versions 1.2.1 through 1.11.0

Description A stored cross-site scripting issue exists in the EmbedElement::buildDestructed() function. The software fails to apply HTML escaping when rendering nested Markdown image alt text and URLs. This allows authenticated users to embed malicious HTML within the alt text of an image located inside a link across entries, comments, posts, messages, or bios, leading to the execution of arbitrary scripts in the browsers of users who view the content.

Recommendations Update Mbin to version 1.11.1 or later.
