Summary
Mezzanine CMS has a Stored Cross-Site Scripting (XSS) vulnerability in the displayable_links_js function
Details

Mezzanine CMS, in versions prior to 6.1.1, contains a Stored Cross-Site Scripting (XSS) vulnerability in the admin interface. The vulnerability exists in the "displayablelinksjs" function, which fails to properly sanitize blog post titles before including them in JSON responses served via "/admin/displayablelinks.js". An authenticated admin user can create a blog post with a malicious JavaScript payload in the title field, then trick another admin user into clicking a direct link to the "/admin/displayablelinks.js" endpoint, causing the malicious script to execute in their browser.
