Deeper analysis
CVE-2025-30561 is a Cross-Site Request Forgery (CSRF) vulnerability in the CAS Maestro WordPress plugin developed by Henrique Mouta, which enables Stored Cross-Site Scripting (XSS). The flaw affects CAS Maestro versions from an unspecified initial release through 1.1.3 and is classified under CWE-352 with 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).
Attackers can exploit this vulnerability remotely over the network with low attack complexity and no required privileges, though it demands user interaction. A threat actor tricks an authenticated user, such as a site administrator, into submitting a forged request via a malicious webpage, resulting in the storage of an XSS payload on the target site. Successful exploitation changes the scope and grants low-level impacts on confidentiality, integrity, and availability.
