CVE-2025-49271Network attack vector

Unauthenticated local file inclusion via tab parameter

Published Aug 14, 2025 · Updated May 12, 2026

Local file inclusion in GravityWP – Merge Tags 1.4.4 and earlier allows remote attackers to include server files through a crafted tab parameter. The plugin uses the unvalidated tab request parameter to select a PHP file for inclusion, allowing attacker-controlled traversal into local files. A privileged user must open the crafted request, and code execution additionally requires an includable local file containing PHP code.
