Summary

In Supervisor through 4.0.2, an unauthenticated user can read log files or restart a service. Note: The maintainer responded that the affected component, inet_http_server, is not enabled by default but if the user enables it and does not set a password, Supervisor logs a warning message. The maintainer indicated the ability to run an open server will not be removed but an additional warning was added to the documentation

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
