Deeper analysis
CVE-2025-26751 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the Alphabetic Pagination WordPress plugin by Fahad Mahmood. The issue affects all versions of the plugin from n/a through 3.2.1 inclusive.
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 required privileges, but necessitating user interaction. Remote attackers can exploit it by tricking authenticated or unauthenticated users into interacting with maliciously crafted input reflected in web page generation, potentially achieving low impacts on confidentiality, integrity, and availability within a changed scope.

Information output filtering directly prevents reflected XSS by encoding or sanitizing user inputs reflected in dynamically generated web pages.
Information input validation rejects or sanitizes malicious inputs before they are processed and reflected by the WordPress plugin.
Flaw remediation requires identifying, reporting, and patching the specific XSS vulnerability in the Alphabetic Pagination plugin.
