CVE-2026-30242

Estado: AnalizadaAlta (8.5)—

Plane is an an open-source project management tool. Prior to version 1.2.3, the webhook URL validation in plane/app/serializers/webhook.py only checks ip.is_loopback, allowing attackers with workspace ADMIN role to create webhooks pointing to private/internal network addresses (10.x.x.x, 172.16.x.x, 192.168.x.x, 169.254.169.254, etc.). When webhook events fire, the server makes requests to these internal addresses and stores the response — enabling SSRF with full response read-back. This issue has been patched in version 1.2.3.

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.

CWE-918 (SSRF) en validación de webhook con AV:N/PR:L permite a atacantes autenticados hacer que el servidor acceda a direcciones internas (10.x.x.x, 169.254.169.254) y lea respuestas; requiere rol ADMIN pero no privilegios de red adyacente.

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.
