CVE-2025-68927

Estado: AnalizadaAlta (7.3)—

Libredesk is a self-hosted customer support desk. Prior to version 0.8.6-beta, LibreDesk is vulnerable to stored HTML injection in the contact notes feature. When adding notes via POST /api/v1/contacts/{id}/notes, the backend automatically wraps user input in <p> tags. However, by intercepting the request and removing the <p> tag, an attacker can inject arbitrary HTML elements such as forms and images, which are then stored and rendered without proper sanitization. This can lead to phishing, CSRF-style forced actions, and UI redress attacks. This issue has been patched in version 0.8.6-beta.

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.

XSS almacenado en notas de contactos (CWE-79) requiere interacción del usuario (UI:P) para ver el contenido inyectado. Los impactos son phishing mediante HTML/formularios inyectados y ejecución de JavaScript en el navegador.

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.
