  "account": "Owncast is a self-hosted live streaming server, designed for one person and often utilized by communities, conferences, or personal channels. With 3,121 instances found, the public-by-design nature of the application presents unique security considerations. Unlike other applications, Owncast must remain reachable, and its security relies on protecting the administration interface. If the admin path is secured only by a password and left unchanged, the potential for compromise increases. The vulnerabilities include unauthorized streaming content, audience privacy breaches, and resource abuse. To mitigate these risks, it is crucial to run the process as a dedicated, unprivileged user with limited access and harden the security by changing default credentials, limiting network and filesystem access, and keeping the application up-to-date. Additionally, using a reverse proxy with TLS and assigning the process its own user account further strengthens the security posture. Personal instances should assume they will be discovered and limit the exposed functionality to match the intended public presence.",
