CVE-2026-35576

Estado: AnalizadaAlta (8.7)—

ChurchCRM is an open-source church management system. Prior to 7.0.0, a stored cross-site scripting (XSS) vulnerability exists in ChurchCRM within the Person Property Management subsystem. This issue persists in versions patched for CVE-2023-38766 and allows an authenticated user to inject arbitrary JavaScript code via dynamically assigned person properties. The malicious payload is persistently stored and executed when other users view the affected person profile or access the printable view, potentially leading to session hijacking or full account compromise. This vulnerability is fixed in 7.0.0.

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 (CWE-79) ejecutado en navegador de otros usuarios; requiere autenticación (PR:L) e interacción (UI:R), pero el vector CVSS lo clasifica como explotación remota de cliente (T1189). Impactos: JavaScript inyectado (T1059.007) y potencial secuestro de sesión/compromisos de cuenta (T1078).

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.
