In plain language

AI Worth attention

Adobe ColdFusion versions 2025.9, 2023.20 and earlier have a serious input-checking flaw that can let an attacker run code on the server, so small businesses should act by upgrading using the fix from Adobe’s APSB26-68.

Executive summary

ColdFusion has an Improper Input Validation issue (CWE-20) where crafted input can be processed in a way that allows arbitrary code execution in the context of the current user; Adobe has a remediation in APSB26-68, but there is no confirmed CISA KEV listing or public exploit code on record.

What to do now

  1. Check your ColdFusion version (confirm whether you are on 2025.9 or 2023.20, or earlier).
  2. If you are affected, upgrade ColdFusion following Adobe’s remediation guidance in APSB26-68 (install the patched build specified there).
  3. After upgrading, verify the service is running the expected patched build and that any exposed public endpoints still respond normally.
