CVE-2023-34014Network attack vector

Authenticated layout modification via missing capability checks

Published Dec 13, 2024 · Updated Apr 28, 2026

Missing authorization in Grid Plus 1.3.2 and earlier allows remote authenticated users to add, update, or delete grid layouts. The grid_plus_save_layout_callback and grid_plus_delete_callback functions perform privileged layout operations without capability checks. Subscriber-level access is sufficient, and exploitation changes or removes site layout data without disclosing confidential data.
