CVE-2026-47931
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 2023.19, 2025.8 and earlier are affected by an Improper Input Validation vulnerability that could result in arbitrary code execution in the context of the current user. An attacker with high privileges could exploit this vulnerability to execute arbitrary code. The vulnerable component is restricted to an administrative network zone by default. 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 · moderate confidenceColdFusion versions 2023.19, 2025.8 and earlier contain an improper input validation vulnerability that allows attackers with high privileges to execute arbitrary code in the context of the current user. No user interaction is required for exploitation. The CVSS scope change indicates the vulnerability impacts components beyond the vulnerable component 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.
-
Check installed ColdFusion versionAccess the ColdFusion Administrator console or check the version file (typically at /CFIDE/adminapi/base.cfc?method=getVersion or through the About ColdFusion page in Administrator)Affected if Version is 2023.x where x <= 19, or 2025.x where x <= 8, or any version labeled as 2023 or 2025 without a higher update number
-
Verify high-privilege user accounts existReview user accounts in ColdFusion Administrator under Security > User Manager. Check for accounts with Administrator or Rich Internet Application (RIA) privilegesAffected if Any high-privilege accounts (Administrator, RIA Administrator) are present in the system
-
Confirm administrative interface is exposedCheck if the ColdFusion Administrator console (typically at /CFIDE/administrator/) is accessible from the network or is not restricted by IP or authentication barriersAffected if The Administrator console is accessible without additional network-level restrictions
-
Review for recent administrative actionsExamine ColdFusion logs in the /cfusion/logs/ directory, particularly administrator.log and exception.log, for any unexpected or suspicious code execution entriesAffected if Logs show unfamiliar code execution, especially from accounts not typically performing such actions
-
Check for unauthorized scheduled tasks or CFCsReview scheduled tasks in ColdFusion Administrator (under Debugging & Logging > Scheduled Tasks) and check the /cfusion/customtags/ or web root for unfamiliar .cfc or .cfm filesAffected if Scheduled tasks exist that were not created by authorized administrators, or unknown custom tags/CFCs are present
Your environment is affected if you are running ColdFusion 2023 version 19 or earlier, or ColdFusion 2025 version 8 or earlier, AND the Administrator interface or high-privilege accounts are accessible to authenticated users.

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 · scopedApply vendor-supplied patches for ColdFusion 2023 and 2025 when released. Until then, limit administrative access to trusted users only and monitor for suspicious administrative activities.
ColdFusion 2023 update to version 2023.20 or later; ColdFusion 2025 update to version 2025.9 or later
- 1. Back up your current ColdFusion installation and all associated data.
- 2. Review Adobe's official ColdFusion release notes for the latest update versions.
- 3. Download the latest ColdFusion 2023 update (version 2023.20 or later) from Adobe's official download center.
- 4. Apply the update by running the installer on your ColdFusion 2023 instance.
- 5. Alternatively, if using ColdFusion 2025, download and apply version 2025.9 or later.
- 6. After installation, restart the ColdFusion Application Server service.
- 7. Verify the update was successful by checking the ColdFusion Administrator > Settings > Version Info page.
- 8. Test critical applications to ensure functionality remains intact after the update.
