Description

The Streamit WordPress theme before 4.5.2 does not perform any authorization or nonce verification on one of its unauthenticated AJAX routes, which invokes an attacker-supplied PHP function with an attacker-supplied argument array, allowing unauthenticated attackers to call arbitrary functions (for example to create an administrator account), leading to privilege escalation and remote code execution.

Affected products and versions

  • Unknown Streamit — Before 4.5.2
