Deeper analysis

CVE-2025-23898 is a Cross-Site Request Forgery (CSRF) vulnerability, classified under CWE-352, in the WordPress plugin "Apply with LinkedIn buttons" by ivobrett. The flaw allows Stored XSS and affects all versions from n/a through <= 2.3. 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) and was published on 2025-01-16T21:15:31.497.

Unauthenticated attackers can exploit this vulnerability remotely with low attack complexity by tricking users into performing unintended actions, such as via a malicious webpage. Successful exploitation leads to Stored XSS, enabling limited impacts on confidentiality, integrity, and availability in a changed scope, such as executing scripts in the context of the WordPress site for other users.
