CVE-2025-25126Network attack vector

Stored script injection via missing nonce validation

Published Feb 7, 2025 · Updated Apr 28, 2026

Cross-site request forgery in zmseo ZMSEO 1.14.1 and earlier allows remote attackers to inject stored scripts through forged settings requests. A settings-update function omits or incorrectly performs WordPress nonce validation, accepting attacker-controlled values that are stored and later rendered as script content. Exploitation requires an administrator to act on a crafted link or request, after which the stored script executes in visitors' browsers and can alter displayed content or access session-available data.
