Please report vulnerabilities privately via GitHub private vulnerability reporting (Security tab → "Report a vulnerability"). Do not open a public issue for security problems.
You can expect an initial response within a few days. Please include a reproduction and the MeTube release version (visible in the UI footer).
MeTube is continuously released; only the latest release is supported. Update to the current Docker image before reporting.
MeTube ships without authentication by design — it is intended to run on a trusted network or behind an authenticating reverse proxy (see the wiki). Reports that reduce to "the UI is reachable without a login" are expected behavior, not vulnerabilities.
