## Affected

- TaskingAI: through 0.3.0

## Description

TaskingAI through 0.3.0 contains a server-side request forgery vulnerability that allows authenticated attackers to make the backend send arbitrary HTTP requests by supplying an unvalidated OpenAPI servers[0].url in a user-defined action. Attackers holding a project API key or console admin login can create an action pointing to loopback, internal or cloud metadata addresses and run it via POST /actions/{action_id}/run to read back up to 64 KiB of responses.

## What to do
