CVE-2025-9493: 
WordPress vulnerability analysis and mitigation

The Admin Menu Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'placeholder' parameter in versions up to and including 1.14 due to insufficient input sanitization and output escaping. This vulnerability was discovered and disclosed on September 6, 2025 (NVD).

The vulnerability exists in the plugin's handling of the 'placeholder' parameter, which lacks proper input sanitization and output escaping. This security flaw allows authenticated attackers with Author-level access or higher to inject arbitrary web scripts into pages. These malicious scripts will execute whenever a user accesses an affected page. The vulnerability has been assigned a CVSS v3.1 base score of 6.4 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N (NVD).

When successfully exploited, this vulnerability allows authenticated attackers to inject and execute arbitrary web scripts in the context of other users' browsers. This could lead to theft of sensitive information, session hijacking, or other malicious actions performed in the context of the affected users' sessions (NVD).

Users should upgrade to a version newer than 1.14 when available. Until then, site administrators should carefully review and limit user roles that have Author-level access or higher to trusted users only (NVD).
