CVE-2025-23485

CVE-2025-23485 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the RS Survey WordPress plugin developed by richestsoft (rs-survey). This issue affects all versions of the plugin from n/a through 1.0 inclusive, as 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 payloads into web pages generated by the plugin, leading to script execution in the context of a victim's browser. This enables potential theft of session cookies or other client-side data, with low impacts to confidentiality, integrity, and availability due to the changed scope.
