CWE-20Published: April 6, 2014· Updated: Jun 16, 2026
4.3
CVSS v3.1
Official Description
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."
Technical Analysis
CVE-2013-1946 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
