Title

WordPress Awesome Support Plugin授权缺失漏洞

Description

WordPress Awesome Support Plugin是一个开源的WordPress工单系统插件。 WordPress Awesome Support Plugin存在授权缺失漏洞，该漏洞源于wpas_do_mr_deny_user()函数缺少权限检查，与wpas_do_mr_activate_user()函数不同，未强制执行current_user_can('edit_users')或current_user_can('edit_user', $user_id)，仅依赖未限定目标用户的nonce，攻击者可利用该漏洞在任意用户账户（包括管理员）上设置mr_user_denied标志，永久阻止其审核激活并发送拒绝通知邮件。

CVE-2026-19946 (GCVE-0-2026-19946)

Vulnerability from cvelistv5 – Published: 2026-09-09 05:31 – Updated: 2026-09-11 20:19

Title

Awesome Support <= 6.3.9 - Missing Authorization to Authenticated (Subscriber+) Arbitrary User Denial via 'user_id' Parameter

Summary

The Awesome Support plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 6.3.9. This is due to a missing capability check on the wpas_do_mr_deny_user() function, which unlike its counterpart wpas_do_mr_activate_user() does not enforce current_user_can('edit_users') or current_user_can('edit_user', $user_id), relying solely on a nonce that is not scoped to the target user. This makes it possible for authenticated attackers, with subscriber-level access and above, to set the mr_user_denied flag on any user account — including administrators — permanently blocking their moderated activation and dispatching a denial notification email to the victim.

Severity
