CVE-2025-60249

Estado: AplazadaMedia (6.4)—

vulnerability-lookup 2.16.0 allows XSS in bundle.py, comment.py, and user.py, by a user on a vulnerability-lookup instance who can add bundles, comments, or sightings. A cross-site scripting (XSS) vulnerability was discovered in the handling of user-supplied input in the Bundles, Comments, and Sightings components. Untrusted data was not properly sanitized before being rendered in templates and tables, which could allow attackers to inject arbitrary JavaScript into the application. The issue was due to unsafe use of innerHTML and insufficient validation of dynamic URLs and model fields.

This vulnerability has been fixed by escaping untrusted data, replacing innerHTML assignments with safer DOM methods, encoding URLs with encodeURIComponent, and improving input validation in the affected models.

Se descubrió una vulnerabilidad de cross-site scripting (XSS) en el manejo de la entrada proporcionada por el usuario en los componentes de Bundles, Comments y Sightings. Los datos no confiables no se sanitizaron correctamente antes de ser renderizados en plantillas y tablas, lo que podría permitir a los atacantes inyectar JavaScript arbitrario en la aplicación. El problema se debió a un uso inseguro de innerHTML y una validación insuficiente de URL dinámicas y campos de modelo. Esta vulnerabilidad se ha corregido mediante el escape de datos no confiables, reemplazando las asignaciones de innerHTML con métodos DOM más seguros, codificando URL con encodeURIComponent y mejorando la validación de entrada en los modelos afectados."
