Detailsinfo

A vulnerability has been found in django-cms django CMS up to 5.0.7 and classified as problematic. This vulnerability affects the function get_descendants of the file cms/admin/placeholderadmin.py of the component Move Plugin Endpoint. The manipulation of the argument plugin_parent with an unknown input leads to a permission vulnerability. The CWE definition for the vulnerability is CWE-275. As an impact it is known to affect integrity, and availability. CVE summarizes:

django CMS is an easy-to-use and developer-friendly enterprise content management system powered by Django. Prior to 5.0.8, the move_plugin endpoint in cms/admin/placeholderadmin.py accepts an attacker-controlled plugin_parent value without rejecting a plugin’s own identifier or a descendant identifier. A staff user with plugin-change permission under CMS_PERMISSION can create a parent_id cycle in the plugin tree. The _get_descendants_cte and _get_ancestors_cte queries in cms/models/pluginmodel.py have no cycle guard, so get_descendants() and later rendering, copy, or delete operations can recurse indefinitely or reach a database recursion limit, corrupting the tree and consuming request workers. This issue is fixed in versions 5.0.8.

The advisory is available at github.com. This vulnerability was named CVE-2026-54623 since 06/15/2026. The exploitation appears to be easy. The attack can be initiated remotely. The exploitation needs additional levels of successful authentication. Technical details are known, but there is no available exploit.
