CVE-2026-48316Network attack vector

Unauthenticated arbitrary code execution

Published Jul 6, 2026 · Updated Aug 27, 2026

Improper input validation in Adobe ColdFusion 2025 Update 9 and 2023 Update 20 and earlier allows remote attackers to execute arbitrary code. Adobe has not published the affected component or the invalid input operation that reaches code execution. No authentication or user interaction is required, and successful exploitation runs code in the context of the user under which ColdFusion executes.
