# Adobe ColdFusion 2016 Update 3 and earlier, ColdFusion 11 update 11 and earlier, ColdFusion 10 Update 22 and earlier…

Adobe ColdFusion ships the Apache BlazeDS library, which has a deserialization flaw in its AMF handling. An attacker who can reach the endpoint can send a crafted serialized object and run arbitrary code on the server.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Adobe ColdFusion affected ? fixed ?
- vendor:adobe coldfusion affected = 10.0 fixed ?
- vendor:adobe coldfusion affected = 11.0 fixed ?
- vendor:adobe coldfusion affected = 2016 fixed ?

## Fix

Apply the mitigations from Adobe's vendor advisory, or discontinue use of ColdFusion if mitigations are unavailable (per CISA required action). Exact patched ColdFusion build numbers: unknown.

## From the sources
