Deeper analysis

CVE-2025-25135 is a Cross-Site Request Forgery (CSRF) vulnerability, classified under CWE-352, in the WordPress plugin Custom Links On Admin Dashboard Toolbar (slug: customize-wpadmin) by Victor Barkalov. The flaw enables Stored Cross-Site Scripting (XSS) and affects the plugin from unknown initial versions through 3.3. Published on 2025-02-07, it carries a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L).

Unauthenticated attackers can exploit this vulnerability remotely with low complexity, though it requires user interaction such as an administrator visiting a malicious site or clicking a crafted link. Exploitation via CSRF tricks the victim into submitting a request that stores an XSS payload on the admin dashboard toolbar, potentially allowing attackers to execute scripts in the context of logged-in administrators for session hijacking or further compromise.
