Deeper analysis
CVE-2025-26774 is an Improper Neutralization of Input During Web Page Generation vulnerability, enabling Reflected Cross-site Scripting (XSS) as classified under CWE-79. It affects the WordPress plugin Responsive Modal Builder for High Conversion – Easy Popups (easy-popups) in all versions from n/a through 1.5.0 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 network accessibility, low attack complexity, no privileges required, but user interaction needed, with changed scope and low impacts to confidentiality, integrity, and availability. Remote attackers can exploit it by tricking authenticated or unauthenticated users into interacting with maliciously crafted requests, such as via a reflected payload in a web page, potentially leading to execution of arbitrary scripts in the victim's browser context.

Information output filtering directly neutralizes reflected XSS payloads by encoding or sanitizing user input before inclusion in web pages.
Information input validation prevents malicious scripts from being accepted and processed by validating inputs at entry points to the WordPress plugin.
Flaw remediation requires timely patching of the specific improper neutralization vulnerability in the easy-popups plugin versions up to 1.5.0.
