Project: TableField [1]
Date: 2019-April-17
Security risk: *Critical* 16∕25
AC:Complex/A:User/CI:All/II:All/E:Theoretical/TD:Default [2]
Vulnerability: Remote Code Execution

Description: 
This module allows you to attach tabular data to an entity.

The module doesn't sufficiently determine that the data being unserialized is
the contents of a tablefield when users request a CSV export, which could
lead to Remote Code Execution via Object Injection.

This vulnerability is mitigated by the fact that an attacker must have a role
with the permission 'export tablefield', and be able to insert a payload into
an entity's field.

Solution: 
Install the latest version:

  * If you use the Tablefield module 7.x-3.x branch for Drupal 7.x, upgrade 
to
    tablefield 7.x-3.4 [3]
