Unauthenticated code execution via RDS FILEIO traversal
Published Jun 30, 2026 · Updated Aug 27, 2026
Path traversal in Adobe ColdFusion 2025 Update 9 and earlier and 2023 Update 20 and earlier allows remote attackers to execute code. The RDS FILEIO WRITE operation at /CFIDE/main/ide.cfm accepts an attacker-controlled filesystem path and writes arbitrary content outside the intended directory. RDS must be enabled with authentication disabled; a successful request can place a CFML web shell in the web root and execute it as the ColdFusion service 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.
