Who can exploit this vulnerability and from where?

Exploitation requires a user with a workspace ADMIN role (or equivalent permissions to configure webhooks) within the Plane application. It is not exploitable by anonymous users without such access. However, once an attacker has that role, they can drive SSRF from anywhere they can reach the Plane UI or API.

Does exploitation require network-level access to the internal services?

No. The attacker does not need direct network access to internal services. They only need the Plane server to have that access. The SSRF occurs because the server issues HTTP requests on behalf of the attacker to internal targets that are reachable from the server's network environment.

What is the safest general fix pattern for this type of SSRF issue?

The safest pattern is to strictly limit webhook destinations. This usually means implementing an allowlist of approved domains or services, denying all private and link-local IP ranges (including cloud metadata endpoints), and validating both the original URL and its resolved IP address before making the request.
