This release addresses a security vulnerability (GHSA-g3c8-4qh2-rhrg) where /debug/pprof/* endpoints were not protected by the --auth-filter flag. The endpoints have been moved to the telemetry server and are now correctly gated. See #2924 for details. Credits to @vldevadath for responsible disclosure.
