Deeper analysis

CVE-2025-23788 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, affecting the Easy Filter WordPress plugin by Roni Saha. The issue impacts all versions from n/a through 1.10 inclusive. Published on 2025-02-14T13:15:47.143, 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).

An unauthenticated network-based attacker can exploit this vulnerability by crafting a malicious URL or input that reflects unsanitized user input back into the web page. Exploitation requires user interaction, such as a victim clicking a phishing link or visiting a malicious site while authenticated to the affected WordPress site. Upon success, the attacker achieves arbitrary script execution in the victim's browser context, with changed scope enabling low impacts to confidentiality (e.g., session data exposure), integrity (e.g., data manipulation), and availability.
