Stored script injection via unverified settings request
Published Mar 11, 2025 · Updated Apr 8, 2026
Cross-site request forgery in weDevs Appsero Helper 1.3.2 and earlier allows remote attackers to inject stored scripts through forged requests. The appsero_helper settings page accepts state-changing updates without valid nonce verification, allowing attacker-supplied script content to be stored. Exploitation requires an authenticated site administrator to submit the forged request; the stored script then executes during later page views.
