Who Should Take Action
If you are running any version of Adobe ColdFusion, we recommend reviewing your environment immediately.
ColdFusion 2025: Update to Update 10 or later.
ColdFusion 2023: Update to Update 21 or later.
ColdFusion 2021, 2018, 2016, or earlier: These versions have reached end of life and no longer receive security updates from Adobe. While Adobe's security bulletin applies to supported releases, unsupported versions should be considered at increased security risk because they do not receive fixes for newly discovered vulnerabilities. We strongly recommend upgrading to a supported version of ColdFusion (2023 or 2025) and applying the latest security updates.
Recommended Actions
Schedule a maintenance window to apply the appropriate update or upgrade.
Back up your ColdFusion installation, configuration, and application files.
Download and install the latest supported ColdFusion update from Adobe.
Restart the ColdFusion services after the update is complete.
Verify the installed update level and test your applications to confirm normal operation.
If you are unable to apply the update immediately, implement temporary measures to reduce exposure, such as:
Disable Remote Development Services (RDS) if it is not required.
Restrict external access to the /CFIDE directory and ColdFusion Administrator.
Implement Web Application Firewall (WAF) protections to help detect and block exploit attempts.
Review server logs for suspicious activity.
These measures may reduce risk but do not fully remediate the vulnerability and should only be considered temporary until the appropriate update or upgrade can be completed.
