Deeper analysis
CVE-2025-24646 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the XML for Avito WordPress plugin developed by icopydoc. The issue affects all versions of the plugin from n/a through 2.5.2.
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 reliant on user interaction such as clicking a malicious link. Any unauthenticated remote attacker can leverage this to inject and execute arbitrary scripts in a victim's browser context, potentially leading to limited impacts on confidentiality, integrity, and availability with a changed scope.
