{"cve":"CVE-2026-54623","nvd":{"published":"2026-08-20T18:16:28.013","modified":"2026-10-26T10:10:00.140","status":"Deferred","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H","score":7.1},"cwes":["CWE-674","CWE-835"],"references":["https://github.com/django-cms/django-cms/commit/7642a98ab3170793c0b27b4125dd1f3d318b8a1c","https://github.com/django-cms/django-cms/pull/8645","https://github.com/django-cms/django-cms/releases/tag/5.0.8","https://github.com/django-cms/django-cms/security/advisories/GHSA-8jj7-4v57-frf5"],"products":[],"source":"nvd","synced_at":"2026-10-26T10:28:23.151169805+00:00"},"epss":{"cve":"CVE-2026-54623","score":0.00487,"percentile":0.41637,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-8jj7-4v57-frf5","url":"https://osv.dev/vulnerability/GHSA-8jj7-4v57-frf5","summary":"django CMS: Plugin move endpoint allows cyclic reparenting (DoS)","modified":"2026-09-10T12:25:57.165291091Z","packages":[{"ecosystem":"PyPI","name":"django-cms","purl":"pkg:pypi/django-cms","ranges":["<5.0.8"],"fixed":["5.0.8"]}]},{"id":"PYSEC-2026-3822","url":"https://osv.dev/vulnerability/PYSEC-2026-3822","summary":"django CMS: Plugin move endpoint allows cyclic reparenting (DoS)","modified":"2026-09-10T12:15:03.042639550Z","packages":[{"ecosystem":"PyPI","name":"django-cms","purl":"pkg:pypi/django-cms","ranges":["<5.0.8"],"fixed":["5.0.8"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
