This module enables you to expose Drupal entities as RESTful web services. It provides a machine-readable interface to exchange resources in JSON, XML and RDF.
The module interferes with Drupalβs page cache and allows an attacker to poison the cache with non-HTML page responses, thereby exposing a denial of service vulnerability.
This vulnerability is mitigated by the fact that page caching must be enabled and the anonymous user role must be assigned a RESTWS permission, for example βaccess resource nodeβ.
Drupal core is not affected. If you do not use the contributed RESTful Web Services module, there is nothing you need to do.
