CVE-2025-25125

CVE-2025-25125 is a Cross-Site Request Forgery (CSRF) vulnerability in the fyrebox-shortcode component of the CyrilG Fyrebox Quizzes WordPress plugin. This issue enables Stored Cross-Site Scripting (XSS) and affects Fyrebox Quizzes versions from n/a through 3.1 inclusive. The vulnerability is associated with CWE-352 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), indicating high severity due to its network accessibility and scope change.

Unauthenticated attackers (PR:N) can exploit this vulnerability remotely (AV:N) with low complexity (AC:L), though it requires user interaction (UI:R), such as a victim visiting a malicious site. Exploitation involves tricking an authenticated user into submitting a forged request via CSRF, leading to stored XSS injection. This allows attackers to achieve low impacts on confidentiality, integrity, and availability (C:L/I:L/A:L) within a changed security scope (S:C), potentially executing scripts in the context of other users viewing affected quiz content.
