Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceColdFusion versions 2023.18, 2025.6 and earlier contain an improper input validation flaw that allows attackers to bypass security mechanisms. Successful exploitation requires user interaction, suggesting a web-based attack vector where a victim must perform an action such as clicking a malicious link or submitting crafted input.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify ColdFusion installation and versionAccess the ColdFusion Administrator console (typically at /cfadmin or /cfide/admin) and navigate to the System Information or Settings page to view the installed version. Alternatively, check the installation directory for a version file or check the Windows registry (HKLM\SOFTWARE\Adobe\ColdFusion\CurrentVersion) on Windows servers.Affected if The installed version is ColdFusion 2023.18 or earlier, or ColdFusion 2025.6 or earlier.
-
Verify ColdFusion edition and component availabilityConfirm the ColdFusion edition (Standard, Enterprise, or Developer) via the Administrator console under System Information. Note that the Administrator interface must be accessible for further checks.Affected if Any edition of ColdFusion 2023.18 or earlier, or 2025.6 or earlier is installed.
-
Review ColdFusion server access logs for suspicious patternsInspect log files in the ColdFusion installation logs directory (typically /logs or cfusion/logs) for unusual HTTP requests, especially those with modified headers, unexpected query parameters, or repeated requests from single IP addresses that may indicate exploitation attempts.Affected if Log analysis reveals requests with unusual input patterns, authentication bypass attempts, or unauthorized access indicators.
-
Audit web server connector configurationCheck the web server connector configuration (typically found in the ColdFusion Administrator under Web Server Configuration or in the web server config files like httpd.conf or iis) to ensure standard security headers and input validation rules are present.Affected if Connector configuration shows missing or weakened input validation rules.
You are affected if ColdFusion 2023 version 18 or earlier, or ColdFusion 2025 version 6 or earlier is installed in your environment.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpdate ColdFusion to the latest patched version beyond 2023.18 and 2025.6 to remediate the input validation vulnerability. Review and validate all user-supplied input fields in existing applications as a secondary hardening measure.
ColdFusion 2023 (version 2023.19 or later) or ColdFusion 2025 (version 2025.7 or later)
- Check your current ColdFusion version by navigating to the ColdFusion Administrator dashboard or checking the version information in the installation
- Identify if your version is ColdFusion 2023.18 or earlier, or ColdFusion 2025.6 or earlier
- Download and install the latest available ColdFusion 2023 update (version 2023.19 or later) from Adobe's official ColdFusion downloads page
- Alternatively, download and install the latest available ColdFusion 2025 update (version 2025.7 or later) from Adobe's official downloads
- After upgrading, verify the new version number in the ColdFusion Administrator to confirm the patch was applied
- Review any new security settings or configurations introduced in the update and adjust as needed
