Vulnerability Description

Bludit is vulnerable to Stored Cross-Site Scripting (XSS) in its image upload functionality. An authenticated attacker with content upload privileges (such as Author, Editor, or Administrator) can upload an SVG file containing a malicious payload, which is executed when a victim visits the URL of the uploaded resource.

All versions up to 3.18.2 are considered to be vulnerable, future versions might also be vulnerable.
