CVE-2026-75827
Grav: Blueprint dynamic-data bare-function branch is denylist-gated and omits error_log, giving arbitrary file write
Severidad por fuente
La etiqueta propia de Trivy es CRITICAL. Crítica según GHSA.
Descripción
Grav before 2.0.15 contains an arbitrary file write vulnerability in the Blueprint dynamic-data bare-function validation that uses an incomplete denylist instead of a positive allowlist. Attackers with page-edit or blueprint-config access can invoke the error_log function through a data directive to append PHP payloads to web-accessible files, achieving remote code execution.
