Deeper analysis

CVE-2025-23828 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Stored Cross-site Scripting (XSS) under CWE-79, in the sindhi WordPress Data Guard plugin (wordpress-data-guards). This issue affects WordPress Data Guard versions from n/a through 8, as published on 2025-01-16.

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. An unauthenticated attacker can exploit it remotely by tricking users into actions that store malicious scripts on the site, such as through CSRF leading to Stored XSS, potentially resulting in low impacts to confidentiality, integrity, and availability with a changed scope.
