CVE-2026-54623

Estado: AplazadaAlta (7.1)—

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

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:N/PR:L sin UI indica servicios remotos con privilegios; ciclo en árbol de plugins provoca recursión infinita (DoS de aplicación) y corrupción de datos en base de datos.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
