Technical details

A stored cross-site scripting (XSS) vulnerability exists in Mezzanine CMS v6.1.0 and earlier within the '/blog/blogpost/add' component. The application fails to properly neutralize user-controllable input when processing the source code formatting of a blog post. An authenticated attacker with high privileges (PR:H) can inject a crafted payload into a blog post; when other users or administrators view the published post, the malicious script executes in their browser context. This can be used for session hijacking, site defacement, or performing actions on behalf of other users. As of the advisory date, no patched version has been identified.
