CVE-2026-27307

Application slowdown via undisclosed resource exhaustion

Published Apr 14, 2026 · Updated Apr 14, 2026

Resource consumption in Adobe ColdFusion 2023.18 and 2025.6 and earlier allows remote authenticated users to degrade application speed. Adobe has not disclosed the affected component or the operation that consumes resources from attacker-controlled input. Exploitation requires high privileges and adjacent-network access, and the reported consequence is resource exhaustion that slows the application.
