Deeper analysis
CVE-2025-30621 is a Cross-Site Request Forgery (CSRF) vulnerability in the kornelly Translator WordPress plugin that allows Stored XSS. This issue affects Translator versions from n/a through <= 0.3.
The vulnerability 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 network accessibility, low attack complexity, no required privileges, and user interaction, with changed scope and low impacts to confidentiality, integrity, and availability. Unauthenticated attackers can exploit it by tricking authenticated users into submitting malicious requests, leading to the storage of XSS payloads that execute in the context of other users viewing affected content.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
SC-23 enforces session authenticity mechanisms like anti-CSRF tokens, directly preventing unauthenticated attackers from forging requests to store malicious XSS payloads.
SI-10 requires validation of information inputs, blocking malicious XSS payloads from being accepted and stored via the CSRF vector in the Translator plugin.
SI-15 filters information outputs to prevent execution of any stored XSS payloads when affected content is viewed by other users.
