Deeper analysis
CVE-2025-31459 is a Cross-Site Request Forgery (CSRF) vulnerability in the PasqualePuzio Login Alert WordPress plugin (login-alert) that allows Stored XSS. This issue affects all versions from n/a through 0.2.1 and is associated with CWE-352. The vulnerability has 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).
The vulnerability can be exploited by unauthenticated attackers over the network with low attack complexity, requiring user interaction such as clicking a malicious link. Exploitation involves tricking a victim (typically an authenticated user like an administrator) into submitting a forged request, enabling the storage of malicious XSS payloads on the site. This can lead to low-level impacts on confidentiality, integrity, and availability, with a changed scope to high due to the cross-origin nature of the attack.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
SC-23 enforces session authenticity mechanisms like anti-CSRF tokens to prevent forged requests from storing malicious XSS payloads.
SI-10 requires validation and sanitization of inputs to block XSS payloads from being accepted and stored via CSRF exploitation.
SI-15 mandates output filtering and encoding to prevent execution of any stored XSS payloads originating from the CSRF vulnerability.
