CVE-2026-58493

MEDIUM 5.1 PoC AVAILABLE ALL-YEARS

Published 2026-07-10 · Last modified 2026-07-13 · GitHub_M · NVD: Deferred

grav-plugin-database is the database plugin for Grav CMS. Prior to 1.2.0, Database::__call builds PDO DSN strings by directly concatenating user-configurable YAML values from fields such as host, dbname, charset, server, database, directory, and filename without sanitization or validation, allowing an administrator with plugin configuration access to inject DSN attributes or path traversal values. This issue is fixed in version 1.2.0.
