# Apicurio Registry allows upload of WSDL raising HTTP request

Apicurio Registry's WSDL validator follows import locations inside an uploaded WSDL file when the VALIDITY rule is set to FULL. A user with Developer-role access can make the registry send HTTP requests to arbitrary internal addresses, which is server-side request forgery.

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

## Affected

- maven:io.apicurio:apicurio-registry-schema-util-wsdl affected >= 3.3.0, < 3.3.1 fixed 3.3.1
- maven:io.apicurio:apicurio-registry-schema-util-wsdl affected < 3.2.6 fixed 3.2.6
- vendor:redhat build of apicurio registry affected >= 3.0, <= 3.2 fixed ?

## How to check

- Check the version of `io.apicurio:apicurio-registry-schema-util-wsdl` in your build files or dependency tree (e.g. `mvn dependency:tree | grep apicurio-registry-schema-util-wsdl`).
- Check whether the WSDL artifact type is in use and whether the VALIDITY rule is set to FULL in the registry configuration.

## Fix

- `io.apicurio:apicurio-registry-schema-util-wsdl` `3.3.1` for the 3.3.x line
- `io.apicurio:apicurio-registry-schema-util-wsdl` `3.2.6` for versions below 3.2.6

## From the sources

A flaw was found in Apicurio Registry. The WSDLReaderAccessor creates a wsdl4j WSDLReader without disabling the javax.wsdl.importDocuments feature. When the VALIDITY rule is set to FULL, an attacker with Developer-role access can upload a WSDL document containing attacker-controlled import locations, causing the registry to issue HTTP requests to arbitrary internal URLs (server-side request forgery).
