The vulnerability CVE-2024-39659 in WP-PostRatings is due to CWE-79, improper neutralization of input during web page generation, resulting in stored cross-site scripting (XSS). This allows an attacker with at least low privileges and requiring user interaction to inject malicious scripts that can impact confidentiality, integrity, and availability to a limited extent. The CVSS 3.1 vector AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L reflects network attack vector, low attack complexity, low privileges required, user interaction required, scope changed, and low impact on confidentiality, integrity, and availability. The affected versions include all versions up to 1.91.1. No patch or official remediation has been published yet.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected site, potentially leading to limited disclosure of information, modification of content, or disruption of availability. The impact is limited by the requirement for user interaction and low privileges. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider restricting privileges to trusted users and be cautious with user-generated content.
