Database redirection via unsanitized DSN construction
Published Jul 10, 2026 · Updated Jul 10, 2026
DSN injection in the Grav Database plugin before 1.2.0 allows remote authenticated users to redirect database connections. Database::__call concatenates YAML host, database, charset, server, directory, and filename values into PDO DSNs without rejecting delimiters or traversal sequences. Grav plugin-configuration administrator access is required; exploitation can reach arbitrary SQLite files, alter connection security, or scan internal services.
