CVE-2025-31475

Estado: AnalizadaMedia (6.6)—

tarteaucitron.js is a compliant and accessible cookie banner. A vulnerability was identified in tarteaucitron.js prior to 1.20.1, where the addOrUpdate function, used for applying custom texts, did not properly validate input. This allowed an attacker with direct access to the site's source code or a CMS plugin to manipulate JavaScript object prototypes, leading to potential security risks such as data corruption or unintended code execution. An attacker with high privileges could exploit this vulnerability to modify object prototypes, affecting core JavaScript behavior, cause application crashes or unexpected behavior, or potentially introduce further security vulnerabilities depending on the application's architecture. This vulnerability is fixed in 1.20.1.

Se identificó una vulnerabilidad en tarteaucitron.js antes de la versión 1.20.1, donde la función addOrUpdate, utilizada para aplicar textos personalizados, no validaba correctamente la entrada. Esto permitía a un atacante con acceso directo al código fuente del sitio o a un complemento de CMS manipular prototipos de objetos JavaScript, lo que conllevaba posibles riesgos de seguridad, como corrupción de datos o ejecución de código no intencionada. Un atacante con privilegios elevados podría explotar esta vulnerabilidad para modificar prototipos de objetos, lo que afectaría el comportamiento principal de JavaScript, provocaría fallos en la aplicación o comportamientos inesperados, o incluso introduciría vulnerabilidades de seguridad adicionales según la arquitectura de la aplicación. Esta vulnerabilidad se corrigió en la versión 1.20.1."
