Exposure of Sensitive Information Through Data Queries vulnerability in Drupal RESTful Web Services allows Forceful Browsing.This issue affects RESTful Web Services: from 7.X-2.0 before 7.X-2.10.

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.

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.

The RESTful Web Services (RESTWS) module 7.x-1.x before 7.x-1.3 and 7.x-2.x before 7.x-2.0-alpha5 for Drupal, when page caching is enabled and anonymous users are assigned RESTWS permissions, allows remote attackers to cause a denial of service via a GET request with an HTTP Accept header set to a non-HTML type, which can "interfere with Drupal's page cache."

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.

Multiple cross-site request forgery (CSRF) vulnerabilities in the RESTful Web Services (RESTWS) module 7.x-1.x before 7.x-1.1 and 7.x-2.x before 7.x-2.0-alpha3 for Drupal allow remote attackers to hijack the authentication of arbitrary users via unknown vectors.
