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.","state":0,"publishedAt":"2026-08-21T22:40:12.771+00:00","modifiedAt":"2026-08-25T16:44:36.584+00:00","affected":[{"ecosystem":"Vendor product","name":"arc","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Basekick-Labs\",\n                    \"product\": \"arc\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 26.06.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","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,"severity":"HIGH"}],"references":["https://github.com/Basekick-Labs/arc/security/advisories/GHSA-j93g-rp6m-j32m","https://github.com/Basekick-Labs/arc/commit/32a4091fb949f9cf060cdd804a07f6450dc426a8","https://github.com/Basekick-Labs/arc/releases/tag/v26.06.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-48050","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-48050","identifiers":["CVE-2026-48050"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
