Deeper analysis

CVE-2025-23844 is a Cross-Site Request Forgery (CSRF) vulnerability, classified under CWE-352, in the Custom Widget Classes WordPress plugin by Jamsheer K. It affects all versions from n/a through 1.1, 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), indicating high severity due to network accessibility, low attack complexity, no required privileges, user interaction, changed scope, and low impacts across confidentiality, integrity, and availability.

The vulnerability enables exploitation by unauthenticated attackers over the network who can trick authenticated users into performing unintended actions via forged requests, requiring user interaction such as clicking a malicious link. Successful exploitation changes the scope of impact, potentially allowing limited disruption to confidentiality, integrity, and availability for affected users or the application.
