CVE-2026-11984Network attack vector

Unauthenticated code disclosure via unchecked debug parameter

Published Sep 16, 2026 · Updated Sep 16, 2026

Authorization bypass in Spacetime Ad Inserter 2.8.16 and earlier allows remote attackers to read disabled header and footer code. The request handler trusts the ai-debug-code URL parameter without a capability check and returns administrator-configured code blocks that normal page rendering suppresses. No account is required; exposure is limited to configured header and footer content disabled from public display, including scripts or other site code.
