CVE-2026-47930
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 a Security feature bypass. A low-privileged attacker could leverage this vulnerability to bypass security measures and gain unauthorized read and write access. Exploitation of this issue does not require user interaction.
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 2023.19, 2025.8 and earlier contain an improper input validation vulnerability that allows low-privileged attackers to bypass security measures. This enables unauthorized read and write access without requiring any user interaction.

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 console at /CFIDE/administrator/ and check the version displayed on the login or home page, or check the version via the installer or registry on the serverAffected if The version shown is 2023.x where x is 19 or lower, or 2025.x where x is 8 or lower
-
Verify ColdFusion web interface is accessibleConfirm that the ColdFusion web administrator interface at /CFIDE/administrator/ is reachable over the networkAffected if The web interface is exposed and accessible to network users (this is required for the vulnerability to be exploitable)
-
Check for low-privileged user accountsReview ColdFusion user accounts in the Administrator under Security > User Manager to identify accounts with limited or low-privilege rolesAffected if Low-privileged user accounts exist in the ColdFusion system (these could be exploited to bypass security)
You are affected if your ColdFusion 2023 installation is version 19 or earlier, or your ColdFusion 2025 installation is version 8 or earlier, and the web administrator interface is network-accessible.
Generated from the published advisory. Verify against your own configuration.
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 · scopedUpgrade to the patched ColdFusion versions as specified in Adobe's security bulletin. Additionally, implement strict input validation and sanitization on all user-supplied data across the application.
ColdFusion 2023.20 or later; ColdFusion 2025.9 or later
- 1. Identify your current ColdFusion installation version (2023.x or 2025.x)
- 2. For ColdFusion 2023: Upgrade to version 2023.20 or later
- 3. For ColdFusion 2025: Upgrade to version 2025.9 or later
- 4. After upgrading, verify the ColdFusion services restart successfully
- 5. Test that the security feature bypass vulnerability is remediated by validating that input validation controls are properly enforced
- 6. Review Adobe's release notes for the specific security fixes included in the new version
