CVE-2025-49345Network attack vector

Stored XSS via missing nonce validation

Published Dec 31, 2025 · Updated Dec 31, 2025

Cross-site request forgery in mg12 WP-EasyArchives 3.1.2 and earlier allows remote attackers to store script content through a forged request. The affected function accepts a state-changing request without valid WordPress nonce verification; public sources do not identify the function or persisted field. Exploitation requires a logged-in site administrator to follow a malicious link or submit an attacker-controlled form, after which the stored content executes in a browser.
