CVE-2025-12377Network attack vector

Author-level gallery modification via unchecked AJAX handlers

Published Nov 13, 2025 · Updated Nov 13, 2025

Missing authorization in Envira Gallery 1.12.0 and earlier allows remote authenticated users to modify arbitrary galleries through AJAX requests. Several handlers in includes/admin/ajax.php accept attacker-selected gallery and image identifiers and perform gallery mutations without verifying a WordPress capability. Author-level access is sufficient to remove images from galleries owned by other users, while the public record does not enumerate every exposed action.
