CVE-2026-48277
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedColdFusion versions 2025.9, 2023.20 and earlier are affected by an Improper Input Validation vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue does not require user interaction. Scope is changed.
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 · high confidenceColdFusion versions 2025.9, 2023.20 and earlier contain an improper input validation vulnerability that allows unauthenticated attackers to execute arbitrary code in the context of the current user without any user interaction. The CVSS scope change indicates the vulnerability can impact components beyond the vulnerable ColdFusion instance itself.

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 installed ColdFusion versionAccess the ColdFusion Administrator interface and navigate to the 'System Information' or 'Settings' page to view the exact version number. Alternatively, check the version from the ColdFusion installation directory or by querying the administrator endpoint if available.Affected if The installed version is 2023 (any build up to and including 20) or 2025 (any build up to and including 9)
-
Confirm ColdFusion edition and buildVerify the exact build number from the ColdFusion Administrator System Information page or by locating the version.txt or installer log files in the installation directory.Affected if The build number matches 2023.20 or earlier, or 2025.9 or earlier
-
Verify ColdFusion is exposed to networkConfirm that the ColdFusion web interface (port 8500 or configured HTTP port) is accessible from network segments accessible to untrusted users. Check firewall rules and reverse proxy configurations.Affected if The ColdFusion administrator or web services are exposed to unauthenticated network access
If your installed ColdFusion version is 2023 (through build 20) or 2025 (through build 9) and the interface is network-accessible, you are affected by this vulnerability.

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.
From vendor dataApply the vendor patch by upgrading ColdFusion to the latest patched version as specified in Adobe's security advisory. Prioritize immediate deployment given the critical severity and unauthenticated exploitation vector.
