CVE-2025-29778

Estado: AnalizadaAlta (8)—

Kyverno is a policy engine designed for cloud native platform engineering teams. Prior to version 1.14.0-alpha.1, Kyverno ignores subjectRegExp and IssuerRegExp while verifying artifact's sign with keyless mode. It allows the attacker to deploy kubernetes resources with the artifacts that were signed by unexpected certificate. Deploying these unauthorized kubernetes resources can lead to full compromise of kubernetes cluster. Version 1.14.0-alpha.1 contains a patch for the issue.

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.

Acceso remoto a servicios (Kyverno) con PR:H; impacto: escalada de privilegios en clúster K8s (root) y despliegue de recursos no autorizados (web shell equivalente).

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.
