CVE-2025-30284
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 a Deserialization of Untrusted Data vulnerability that could result in arbitrary code execution in the context of the current user. A high-privileged attacker could leverage this vulnerability to bypass security protections and execute code. Exploitation of this issue requires 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 a Deserialization of Untrusted Data vulnerability that allows a high-privileged attacker to bypass security protections and execute arbitrary code in the current user's context. Exploitation requires user interaction and results in a scope change, indicating the impact extends beyond the vulnerable component.

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 and navigate to the System Information page, or inspect the version.properties file in the ColdFusion installation directory under libAffected if Version displayed is 2021.18 or earlier, 2023.12 or earlier, or any 2025.0 build (including 2025.0)
-
Confirm ColdFusion edition and update levelRun the cfadmin API or check the ColdFusion update installer history via the Administrator Updates pageAffected if No security patches from Adobe after the 2021.18, 2023.12, or 2025.0 releases have been applied
-
Review user privilege assignmentsAccess ColdFusion Administrator Security settings and enumerate all users with high-privileged roles such as Administrator or DesignerAffected if Multiple high-privileged accounts exist or accounts with broad system access are present
-
Examine ColdFusion logs for deserialization activitySearch the coldfusion11 logs and application logs in the ColdFusion runtime logs directory for patterns involving object deserialization, untrusted input, or scope changesAffected if Logs contain unexpected deserialization calls, scope modifications, or command executions that do not match legitimate administrator actions
The environment is affected if running any unpatched ColdFusion 2021 version 18 or earlier, ColdFusion 2023 version 12 or earlier, or ColdFusion 2025.0, combined with accessible high-privileged accounts that could be targeted for user interaction exploitation.

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 Adobe's official security patches to upgrade ColdFusion beyond the affected versions (2023.12, 2021.18, 2025.0) and restrict high-privileged user access while monitoring for suspicious user interactions.
ColdFusion 2023 to 2023.13+; ColdFusion 2021 to 2021.19+; ColdFusion 2025 to 2025.1+
- Identify your current ColdFusion version (2021, 2023, or 2025) and update channel
- For ColdFusion 2023: upgrade to version 2023.13 or later from helpx.adobe.com
- For ColdFusion 2021: upgrade to version 2021.19 or later from helpx.adobe.com
- For ColdFusion 2025: upgrade to version 2025.1 or later from helpx.adobe.com
- After upgrading, verify the ColdFusion Administrator console loads without errors
- Test critical application functionality to ensure the update did not break existing workflows
