CVE-2026-92459

Estado: AplazadaAlta (7.1)—

yshop-crm through 2.1.3 contains a missing authorization vulnerability in the CrmCluesController receiveCustomer endpoint that allows authenticated back-office users to claim sales leads without proper permission checks. Attackers can invoke the lead-claim endpoint to reassign leads from other employees to themselves by overwriting the ownerUserId field, with no access logging or quota validation to prevent bulk lead theft.

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.

Explotación de servicio remoto (endpoint CRM) por usuario autenticado sin verificación de autorización (CWE-862). Impacto: elevación de privilegios funcionales (reasignación de leads) y manipulación de datos de negocio sin logs de auditoría.

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.
