Deeper analysis

CVE-2025-23455 is a Cross-Site Request Forgery (CSRF) vulnerability, classified under CWE-352, in the WP VTiger Synchronization plugin (msstiger) developed by Master Software Solutions. This flaw enables Stored XSS and affects all versions of the plugin from its initial release through 1.1.1. The vulnerability was published on 2025-01-16 and 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 by tricking authenticated users into interacting with malicious content, such as visiting a crafted webpage. Exploitation via CSRF allows attackers to submit unauthorized requests that result in Stored XSS, achieving low impacts on confidentiality, integrity, and availability with a changed scope.
