CVE-2026-57693Network attack vector

Subscriber-level script execution via undisclosed XSS

Published Jul 13, 2026 · Updated Jul 13, 2026

Cross-site scripting in Igor Funa Ad Inserter 2.8.11 and earlier allows remote authenticated users to execute scripts in visitors' browsers. Public advisories do not identify the affected request field, code path, or exact failure to neutralize untrusted input before output. Subscriber access is sufficient to submit the payload, and execution requires another user to visit affected content.
