CVE-2025-8682Public exploitNetwork attack vector

Unauthorized plugin installation via unchecked AJAX handler

Published Oct 11, 2025 · Updated Apr 8, 2026

Missing authorization in ThemeAnsar Newsup 5.0.10 and earlier allows attackers to install the ansar-import plugin through WordPress AJAX. The newsup_admin_info_install_plugin function handles the install_act_plugin action without checking installation capabilities or validating a nonce. The action is network-reachable through admin-ajax.php; the CNA describes unauthenticated access, while its published CVSS vector requires low privileges.
