About Adobe Coldfusion
CVE-2026-47931 affects Adobe Coldfusion, a product from Adobe. Before acting, confirm where Adobe Coldfusion runs in your estate, who owns it and whether it is reachable from the internet, because exposure decides real risk more than the score alone.
What the flaw is
In plain terms: ColdFusion 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.
The weakness class is Improper Input Validation. The software trusts input without checking it is safe.
Based on its CVSS vector, the flaw needs local or adjacent access, needs some level of access, and needs no user interaction. Apply the vendor fix and confirm exposure on internet facing and business critical assets first.

How to detect it
- Inventory every instance of Adobe Coldfusion and record the running version against the affected range above.
- Check external attack surface scans for internet facing instances of the component.
- Review logs on affected systems for unusual requests, errors or new processes around the vulnerable function.
- Confirm with an authenticated vulnerability scan once your scanner has a check for this CVE.
How to fix it
- Apply the fixed version of Adobe Coldfusion named in the vendor advisory.
- If patching must wait, restrict network access to the affected service and put it behind authentication or a web application firewall rule.
- Rescan after the change to prove the exposure is gone, then close the ticket.
