CyberRota Analysis
AI-GeneratedVersions of Arc prior to 26.06.1 are vulnerable due to unauthenticated access to the `/debug/pprof/*` endpoints, which can expose sensitive profiling data. This high-severity vulnerability (CVSS 8.8) allows attackers to exploit the profiling interface without authentication, potentially leading to information disclosure or further attacks. Organizations using affected versions should prioritize immediate patching or implement recommended workarounds to secure their deployments.

Original NVD Description
Arc is an open, SQL-native time-series database for telemetry. Versions prior to 26.06.1 register Go's `net/http/pprof` handlers at `/debug/pprof/*` via `app.Use(pprof.New())` in `internal/api/server.go`, and `/debug/pprof` is added to `PublicPrefixes` in `cmd/arc/main.go`. The auth middleware short-circuits before the token check on prefix match, so the endpoints are reachable without any authentication. Version 26.06.1 contains a patch. Some workarounds are available. Block `/debug/pprof*` at a reverse proxy / load balancer in front of Arc, restrict Arc's API port to known-trusted networks via firewall rules, and/or patch the running build: comment out `app.Use(pprof.New())` in `internal/api/server.go` and rebuild.
