The strongest mitigations our analysis identified are NIST 800-53 SC-23 (Session Authenticity) and SI-10 (Information Input Validation).

Deeper analysis

CVE-2025-26931 is a Cross-Site Request Forgery (CSRF) vulnerability, classified under CWE-352, in the Tribulant Gallery Voting WordPress plugin developed by Tribulant Software. The flaw enables Stored Cross-Site Scripting (XSS) and affects all versions of the plugin from its initial release through 1.2.1. Published on 2025-02-25, it 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 network accessibility and scope change.

Unauthenticated attackers can exploit this vulnerability remotely with low complexity by tricking authenticated users into interacting with malicious content, such as visiting a crafted webpage. This user interaction triggers the CSRF to inject and store an XSS payload on the targeted site, potentially allowing script execution in the context of the WordPress site for subsequent visitors, including administrators.

Mitigation details are available in the Patchstack advisory at https://patchstack.com/database/Wordpress/Plugin/gallery-voting/vulnerability/wordpress-tribulant-gallery-voting-plugin-1-2-1-csrf-to-stored-xss-vulnerability?_s_id=cve.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SC-23 Session Authenticity good match
prevent

Directly mitigates CSRF by requiring session authenticity mechanisms like anti-CSRF tokens to prevent unauthorized requests that inject stored XSS payloads.

SI-10 Information Input Validation good match
prevent

Enforces validation of user inputs to block malicious XSS payloads from being accepted and stored via CSRF exploitation.

SI-15 Information Output Filtering good match
prevent

Filters output to neutralize any stored XSS scripts, preventing their execution in users' browsers including administrators.
