A cross-site scripting (XSS) vulnerability in the component /blog/blogpost/add of Mezzanine CMS v6.1.0 allows attackers to execute arbitrary web scripts or HTML via injecting a crafted payload into a blog post.

Stored Cross-Site Scripting (XSS) in Mezzanine CMS Admin Interface

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 "displayable_links_js" function, which fails to properly sanitize blog post titles before including them in JSON responses served via "/admin/displayable_links.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/displayable_links.js" endpoint, causing the malicious script to execute in their browser.
