CVE-2026-19650

Estado: AnalizadaAlta (7.1)—

GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.2 before 18.11.11, 19.0 before 19.0.8, 19.1 before 19.1.6, and 19.2 before 19.2.4 that under certain conditions could have allowed an unauthenticated user to execute mutations via GET requests due to improper request validation in GraphQL multiplex query handling.

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.

UI:R (requiere interacción: GET request con mutación) → T1203. GraphQL mutations permiten ejecución de código/comandos (T1059) y manipulación de datos (T1565.002) sin autenticación previa.

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.
