Deeper analysis

CVE-2025-23508 is a Cross-Site Request Forgery (CSRF) vulnerability in the OrigoThemes Extra Options – Favicons WordPress plugin (extra-options-favicons), which enables Stored XSS. This issue affects all versions of the plugin from n/a through 1.1.0 inclusive. The vulnerability is rated 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) and is associated with CWE-352.

The vulnerability can be exploited by any network attacker with low attack complexity and no required privileges, though it requires user interaction such as clicking a malicious link. Exploitation involves tricking an authenticated user into submitting a CSRF request that injects a stored XSS payload into the plugin's favicon options. Once stored, the XSS executes in the context of other users viewing affected pages, potentially leading to low-level impacts on confidentiality, integrity, and availability, such as session hijacking or data theft within the site's scope.
