The RESTful Web Services (restws) module 7.x-1.x before 7.x-1.4 and 7.x-2.x before 7.x-2.1 for Drupal does not properly restrict access to entity write operations, which makes it easier for remote authenticated users with the "access resource node" and "create page content" permissions (or equivalents) to conduct cross-site scripting (XSS) or execute arbitrary PHP code via a crafted text field.

Cross-site request forgery (CSRF) vulnerability in the RESTful Web Services (restws) module 7.x-1.x before 7.x-1.2 and 7.x-2.x before 7.x-2.0-alpha4 for Drupal allows remote attackers to hijack the authentication of arbitrary users via unknown vectors.

The RESTWS Basic Auth submodule in the RESTful Web Services module 7.x-1.x before 7.x-1.5 and 7.x-2.x before 7.x-2.3 for Drupal caches pages for authenticated requests, which allows remote attackers to obtain sensitive information via unspecified vectors.
