Description

Rustrak before 0.26.0 contains a server-side request forgery vulnerability that allows users with integrations update permission to send requests to arbitrary destinations by supplying routing_override.url to POST /api/integrations/{id}/test. Attackers can target loopback, private-network and cloud metadata addresses with custom headers and redirects followed, reading non-2xx response bodies returned in the API response.
