Unauthenticated arbitrary code execution
Published Aug 11, 2026 · Updated Aug 11, 2026
Heap-based buffer overflow in Adobe ColdFusion 2023 through 2023.0.22 and 2025 through 2025.0.11 allows remote attackers to execute code. Adobe has not disclosed the affected component, input vector, or memory operation that causes the heap overwrite. Network access without authentication is sufficient, but exploitation requires conditions beyond the attacker's control and runs code as the current user.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <=2023.0.22
- Affected versionversion=0 <=2025.0.11
