description

Plane versions before 1.4.0 do not validate redirect destinations during webhook delivery. An attacker able to create a workspace can cause the worker to request internal resources and retrieve returned data from webhook logs.

Upgrade the Plane package to version 1.4.0 or later.

fixed in 1.4.0
