FKIE_CVE-2026-33229
Vulnerability from fkie_nvd - Published: 2026-04-08 16:16 - Updated: 2026-07-24 23:10
Severity
Summary
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Prior to 17.4.8 and 17.10.1, an improperly protected scripting API allows any user with script right to bypass the sandboxing of the Velocity scripting API and execute, e.g., arbitrary Python scripts, allowing full access to the XWiki instance and thereby compromising the confidentiality, integrity and availability of the whole instance. Note that script right already constitutes a high level of access that we don't recommend giving to untrusted users. This vulnerability is fixed in 17.4.8 and 17.10.1.

Antes de las versiones 17.4.8 y 17.10.1, una API de scripting protegida incorrectamente permite a cualquier usuario con derecho de script eludir el sandboxing de la API de scripting de Velocity y ejecutar, por ejemplo, scripts Python arbitrarios, lo que permite acceso total a la instancia de XWiki y, por lo tanto, comprometiendo la confidencialidad, integridad y disponibilidad de toda la instancia. Tenga en cuenta que el derecho de script ya constituye un alto nivel de acceso que no recomendamos otorgar a usuarios no confiables. Esta vulnerabilidad est\u00e1 corregida en las versiones 17.4.8 y 17.10.1."
