Deeper analysis

CVE-2025-25129 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, affecting the NotFound Callback Request feature in the WordPress plugin Callback Request. This issue impacts all versions from n/a through 1.4, as published on 2025-03-03.

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 it is exploitable over the network with low attack complexity, no privileges required, but necessitating user interaction. Remote attackers can craft malicious inputs that reflect back to victims via the NotFound Callback Request, potentially executing arbitrary scripts in the user's browser context due to the changed scope.
