CVE-2025-22623Network attack vector

Browser script execution via unsanitized POST reflection

Published Mar 6, 2025 · Updated Mar 6, 2025

Reflected XSS in Ad Inserter 2.8.0 allows attackers to execute script in a user's browser through a crafted POST request. In myapp/includes/dst/dst.php, the notice-check branch echoes the POST value directly without validation, sanitization, or output encoding. Exploitation requires active user interaction; successful script execution can read or alter browser-visible data, but the published assessment reports no availability impact.
