Deeper analysis
CVE-2025-23484 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, affecting the Cojecto Predict When WordPress plugin. The issue impacts all versions from n/a through 1.3 inclusive and was 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 network accessibility, low attack complexity, no required privileges, and user interaction such as clicking a malicious link. Remote attackers can exploit it by injecting malicious scripts via unsanitized input reflected in web pages, achieving arbitrary script execution in the victim's browser context with changed scope and low impacts to confidentiality, integrity, and availability.
