Deeper analysis
CVE-2025-23465 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the Vampire Character Manager WordPress plugin (vampire-character). This issue affects all versions of the plugin from n/a through 2.13 inclusive. The vulnerability was published on 2025-03-03T14:15:36.213 and carries a CVSS v3.1 base score of 7.1.
Attackers can exploit this vulnerability remotely over the network (AV:N) with low attack complexity (AC:L), requiring no privileges (PR:N) but user interaction (UI:R), and resulting in a changed scope (S:C) with low impacts to confidentiality, integrity, and availability (C:L/I:L/A:L). Any unauthenticated remote attacker can craft malicious input that reflects unsanitized back to users, such as via a phishing link or malicious webpage, executing arbitrary JavaScript in the victim's browser context upon interaction.

Information Output Filtering directly prevents reflected XSS by encoding or filtering user input reflected in web page generation to block JavaScript execution.
Information Input Validation rejects or sanitizes malicious inputs before they are processed and reflected in web pages, mitigating the improper neutralization vulnerability.
Flaw Remediation requires identifying, reporting, and patching the specific XSS vulnerability in the Vampire Character Manager plugin up to version 2.13.
