{"cve":"CVE-2026-48050","nvd":{"published":"2026-08-21T23:16:25.070","modified":"2026-10-12T16:10:00.220","status":"Deferred","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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.8},"cvss_v3":null,"cwes":["CWE-200","CWE-306","CWE-400"],"references":["https://github.com/Basekick-Labs/arc/commit/32a4091fb949f9cf060cdd804a07f6450dc426a8","https://github.com/Basekick-Labs/arc/releases/tag/v26.06.1","https://github.com/Basekick-Labs/arc/security/advisories/GHSA-j93g-rp6m-j32m"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-48050","score":0.00643,"percentile":0.50519,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-j93g-rp6m-j32m","url":"https://osv.dev/vulnerability/GHSA-j93g-rp6m-j32m","summary":"Arc: Unauthenticated access to Go debug pprof endpoints leaks runtime state and enables CPU-burn DoS","modified":"2026-06-25T23:11:46.654800979Z","packages":[{"ecosystem":"Go","name":"github.com/basekick-labs/arc","purl":"pkg:golang/github.com/basekick-labs/arc","ranges":["<0.0.0-20260520170331-32a4091fb949"],"fixed":["0.0.0-20260520170331-32a4091fb949"]}]},{"id":"GO-2026-5457","url":"https://osv.dev/vulnerability/GO-2026-5457","summary":"Arc: Unauthenticated access to Go debug pprof endpoints leaks runtime state and enables CPU-burn DoS in github.com/basekick-labs/arc","modified":"2026-06-25T23:01:18.241165504Z","packages":[{"ecosystem":"Go","name":"github.com/basekick-labs/arc","purl":"pkg:golang/github.com/basekick-labs/arc","ranges":["<0.0.0-20260520170331-32a4091fb949"],"fixed":["0.0.0-20260520170331-32a4091fb949"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
