CVE-2025-23663Network attack vector

Browser script execution via undisclosed reflected input

Published Mar 3, 2025 · Updated Apr 28, 2026

Reflected XSS in Adrian Vaquez Contexto 1.0 and earlier allows remote attackers to run script in a visitor's browser via crafted requests. The public CNA and Patchstack records do not disclose the affected parameter, function, or output sink that returns unneutralized input in generated HTML. No authentication is required, but a visitor must load attacker-controlled content before script executes in the site's browser origin; no server-side code execution is reported.
