Description

The High-performance JavaScript callback handler module is a light weight callback to bypass most, if not all, of Drupal's bootstrapping process to achieve improved performance.

The module does not sufficiently check whether or not a callback is being properly accessed or filtering for potential XSS or CSRF exploits.

CVE identifier(s) issued

  • A CVE identifier will be requested, and added upon issuance, in accordance with Drupal Security Team processes.

Versions affected

  • High-performance JavaScript callback handler (js) 7.x-1.x versions prior to 7.x-2.1.

Drupal core is not affected. If you do not use the contributed High-performance JavaScript callback handler module, there is nothing you need to do.

Solution

Install the latest version:

  • If you use the js module for Drupal 7.x, upgrade to js 7.x-2.1

Note: this upgrade is not backwards compatible with 7.x-1.x. Existing contrib and custom module implementations of this API will either need to be upgraded, replaced or removed.
