description

Versions of the trigger.dev npm package before 4.5.2 allow alert webhook destinations to target internal network or cloud metadata addresses. An authenticated organization member can cause the control plane to send requests to those addresses by creating an alert webhook channel.

mitigation

Upgrade the trigger.dev npm package to version 4.5.2 or later. Until the upgrade is complete, restrict organization membership and remove or review alert webhook destinations that point to internal or non-public addresses.

fixed in 4.5.2
