CVE-2025-23620

CVE-2025-23620 is an improper neutralization of input during web page generation vulnerability, enabling reflected cross-site scripting (XSS) as classified under CWE-79. It affects the WordPress plugin Captchelfie – Captcha by Selfie (captchelfie-captcha-by-selfie) in all versions from n/a through 1.0.7 inclusive. The vulnerability carries a CVSS v3.1 base score of 7.1, with vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L, indicating high severity due to network accessibility, low complexity, no required privileges, user interaction, and changed scope.

Remote attackers require no privileges to exploit this issue by injecting malicious payloads into inputs that are reflected unsanitized on the web page. Victims must interact, typically by visiting a crafted URL, triggering arbitrary JavaScript execution in their browser context. This allows limited impacts: low confidentiality (e.g., potential session data exposure), integrity (e.g., minor page manipulation), and availability (e.g., brief denial via scripts), with scope expansion possibly affecting site users or resources.
