CVE-2025-30294
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 2023.12, 2021.18, 2025.0 and earlier are affected by an Improper Input Validation vulnerability that could result in a security feature bypass. A high-privileged attacker could leverage this vulnerability to bypass security protections and gain unauthorized read access. Exploitation of this issue does not require user interaction and 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 2023.12, 2021.18, 2025.0 and earlier contain an improper input validation vulnerability that allows a high-privileged attacker to bypass security protections and gain unauthorized read access to sensitive data. The flaw enables read-based information disclosure without requiring user interaction, and the scope change indicates the vulnerability can impact components beyond the 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 console (typically at /cfide/administrator/) and navigate to the System Information or Settings page to view the exact version number. Alternatively, check the version file in the ColdFusion installation directory or use the 'cfadmin' API if available.Affected if The installed version is 2023.12 or earlier, 2021.18 or earlier, or 2025.0 (any version matching the affected ranges).
-
Determine if the instance is network-accessibleVerify whether the ColdFusion web interface (ports 8500 or 80/443 by default) is exposed to untrusted networks or the public internet. Check firewall rules and reverse proxy configurations.Affected if The ColdFusion Administrator or API endpoints are reachable from untrusted networks, allowing a high-privileged attacker to send requests.
-
Confirm high-privileged access existsReview user accounts in the ColdFusion Administrator under Security > User Manager to identify accounts with Administrator-level or elevated privileges that could be leveraged.Affected if High-privileged user accounts (Administrator, Developer, or custom roles with extensive permissions) exist in the system.
-
Check for web-facing endpointsAudit publicly accessible ColdFusion files (.cfm, .cfc) and API endpoints. Review web server configuration (IIS, Apache) and ColdFusion mappings for external-facing paths.Affected if Sensitive ColdFusion endpoints or files that handle data retrieval are exposed to external requests.
A user is affected if their ColdFusion installation version falls within 2023.12 or earlier, 2021.18 or earlier, or 2025.0 AND the instance is accessible to a high-privileged attacker who could exploit the input validation bypass to read sensitive data.

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 the vendor-supplied security patch for this vulnerability to all affected ColdFusion installations. Since this is an input validation bypass, verify that security policies and access controls are properly enforced post-patch.
ColdFusion 2023 Update 12, ColdFusion 2021 Update 18, or latest available ColdFusion 2025 update
- Identify your current ColdFusion version by checking the ColdFusion Administrator or the version file
- Download the appropriate hotfix or update from helpx.adobe.com for your ColdFusion edition
- Apply ColdFusion 2023 Update 12 (or later) for ColdFusion 2023 installations
- Apply ColdFusion 2021 Update 18 (or later) for ColdFusion 2021 installations
- Apply ColdFusion 2025 Update (or later, as available) for ColdFusion 2025 installations
- Restart the ColdFusion services after applying the update
- Verify the update was successful by checking the ColdFusion Administrator version information
