Deeper analysis
CVE-2025-28931 is a Cross-Site Request Forgery (CSRF) vulnerability in the DevriX Hashtags (wp-hashtags) WordPress plugin that allows Stored XSS. This issue affects the plugin from unknown initial versions through version 0.3.2. Published on 2025-03-11, it 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).
The vulnerability can be exploited by unauthenticated attackers (PR:N) over the network (AV:N) with low complexity (AC:L), though it requires user interaction (UI:R). An attacker can trick an authenticated user into performing a state-changing action via a forged request, enabling the storage of malicious XSS payloads on the site. Successful exploitation changes scope (S:C) and results in low impacts to confidentiality, integrity, and availability.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
SC-23 enforces session authenticity mechanisms like anti-CSRF tokens to prevent unauthenticated attackers from tricking users into storing malicious XSS payloads via forged requests.
SI-10 requires validation of information inputs such as hashtag data to block malicious XSS scripts from being stored through CSRF exploitation.
SI-15 filters information outputs to neutralize any stored XSS payloads that might have been injected via the CSRF vulnerability.
