{"id":"CVE-2026-54623","aliases":["GHSA-8jj7-4v57-frf5"],"url":"https://o3.security/vulnerability/CVE-2026-54623","summary":"django CMS: Plugin move endpoint allows cyclic reparenting (DoS)","details":"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.","published":"2026-08-20T18:02:45.599Z","modified":"2026-08-22T03:58:06.517136557Z","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H"},"epss":{"score":0.00345,"percentile":0.27069,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"django-cms","fixedVersion":"5.0.8"}],"fix":{"url":"https://github.com/django-cms/django-cms/commit/7642a98ab3170793c0b27b4125dd1f3d318b8a1c","label":"django-cms/django-cms@7642a98"},"references":[{"type":"WEB","url":"https://github.com/django-cms/django-cms/releases/tag/5.0.8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54623.json"},{"type":"ADVISORY","url":"https://github.com/django-cms/django-cms/security/advisories/GHSA-8jj7-4v57-frf5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54623"},{"type":"FIX","url":"https://github.com/django-cms/django-cms/commit/7642a98ab3170793c0b27b4125dd1f3d318b8a1c"},{"type":"FIX","url":"https://github.com/django-cms/django-cms/pull/8645"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-22T03:58:06.517136557Z"}}
