CVE-2025-30285
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 · moderate confidenceColdFusion versions prior to the specified releases contain a deserialization vulnerability where untrusted data can be deserialized, allowing a high-privileged attacker to bypass security protections and achieve arbitrary code execution. The attack requires user interaction and results in code running in the context of the current user with elevated privileges.

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 interface and navigate to the System Information or Settings page, or check the version.xml file in the lib directory of your ColdFusion installation.Affected if The installed version is 2021.x prior to 2021.18, 2023.x prior to 2023.12, or 2025.x prior to 2025.0.
-
Locate deserialization configuration filesInspect the ColdFusion installation directory for neo-runtime.xml or similar XML configuration files that control deserialization behavior.Affected if The configuration allows deserialization of untrusted data without explicit restrictions or uses default unsafe deserialization settings.
-
Identify exposed serialization endpointsReview web server configuration and ColdFusion mapping files to locate any endpoints that accept serialized data input, particularly those handling Java or CFML object deserialization.Affected if Endpoints accepting serialized data from untrusted sources are publicly accessible without additional validation layers.
-
Check for enabled deserialization featuresExamine the ColdFusion Administrator settings for any enabled serialization-related features such as Flash Remoting, Hessian, or similar protocols that perform automatic object deserialization.Affected if Deserialization features that handle untrusted input are enabled and accessible to users.
-
Review recent access and error logsSearch ColdFusion log files for deserialization-related errors, unusual serialized data patterns, or suspicious deserialization activity in the logs directory.Affected if Logs contain evidence of deserialization attempts with unexpected data formats or payload signatures.
You are affected if your ColdFusion installation version is 2021.x before Update 18, 2023.x before Update 12, or 2025.x before version 5.0, and deserialization features handling untrusted data are accessible in your environment.

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 patch or upgrade ColdFusion to a version beyond 2023.12, 2021.18, or 2025.0 as specified in Adobe's security bulletin. Given the high CVSS and code execution impact, prioritize patching immediately.
ColdFusion 2023 Update 13+, ColdFusion 2021 Update 19+, ColdFusion 2025 Update 1+
- Identify your current ColdFusion version by checking the ColdFusion Administrator or the version number in the installation
- For ColdFusion 2023 users: Upgrade to ColdFusion 2023 Update 13 or later
- For ColdFusion 2021 users: Upgrade to ColdFusion 2021 Update 19 or later
- For ColdFusion 2025 users: Upgrade to ColdFusion 2025 Update 1 or later
- Download the appropriate update from the Adobe ColdFusion downloads page (helpx.adobe.com)
- Apply the update following Adobe's standard ColdFusion update installation procedure
- After updating, verify the ColdFusion services restart successfully
- Confirm the version has been updated by checking the ColdFusion Administrator About page
