Arbitrary post meta updates via missing nonce validation
Published Dec 6, 2025 · Updated Apr 8, 2026
CSRF in xbenx WP Landing Page 0.9.3 and earlier allows remote attackers to update arbitrary post metadata through a forged request. The wplp_api_update_text function accepts the state-changing request without nonce validation and writes attacker-controlled values to arbitrary post meta fields. Exploitation requires an administrator with an authenticated WordPress session to follow a crafted link or otherwise submit the forged request.
