Summary
OpenBullet2 through version 0.3.2 has an authentication bypass vulnerability in the API key authentication middleware. Unauthenticated attackers can gain admin access by supplying an empty X-Api-Key header value, as it is compared against a default empty AdminApiKey string.
Risk Assessment
An attacker can gain full access to the admin console and all API endpoints without valid credentials, leading to complete compromise of the application and its data.
Recommendation
Immediately upgrade OpenBullet2 to a version later than 0.3.2 and configure a strong, non-empty API key.

OpenBullet2 through version 0.3.2 contains an authentication bypass vulnerability in the API key authentication middleware that allows unauthenticated attackers to gain admin access by supplying an empty X-Api-Key header value. Attackers can exploit the middleware's comparison of the supplied header against an empty AdminApiKey default string to access the admin console and all API endpoints without valid credentials.
