An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-48050 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/basekick-labs/arc (Go): affected all versions; fixed in 0.0.0-20260520170331-32a4091fb949\n- github.com/basekick-labs/arc (Go): affected all versions; fixed in 0.0.0-20260520170331-32a4091fb949\n- github.com/basekick-labs/arc (Go): affected all versions; fixed in 0.0.0-20260520170331-32a4091fb949\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-48050/ (Markdown: https://insights.sbomify.com/CVE-2026-48050/index.md)","id":"CVE-2026-48050","markdown":"https://insights.sbomify.com/CVE-2026-48050/index.md","name":"CVE-2026-48050","record":{"aliases":["GHSA-j93g-rp6m-j32m","GO-2026-5457"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Arc time-series database","requires_auth":"none","summary":"Unauthenticated access to Arc database debug endpoints allows attackers to leak runtime state and cause denial of service via CPU exhaustion.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","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","version":"4.0"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"},{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"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.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Arc: Unauthenticated access to Go debug pprof endpoints leaks runtime state and enables CPU-burn DoS","id":"CVE-2026-48050","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":3,"n_references":3,"next":{"headline":"Papra: SSRF via HTTP redirect bypass in webhook delivery","id":"CVE-2026-48051"},"packages":[{"ecosystem":"Go","fixed":["0.0.0-20260520170331-32a4091fb949"],"introduced":["0"],"last_affected":[],"package":"github.com/basekick-labs/arc","purl":null,"source":"GHSA-j93g-rp6m-j32m"},{"ecosystem":"Go","fixed":["0.0.0-20260520170331-32a4091fb949"],"introduced":["0"],"last_affected":[],"package":"github.com/basekick-labs/arc","purl":"pkg:golang/github.com/basekick-labs/arc","source":"GHSA-j93g-rp6m-j32m"},{"ecosystem":"Go","fixed":["0.0.0-20260520170331-32a4091fb949"],"introduced":["0"],"last_affected":[],"package":"github.com/basekick-labs/arc","purl":"pkg:golang/github.com/basekick-labs/arc","source":"GO-2026-5457"}],"prev":{"headline":"@hapi/inert: Static-file confinement bypass via sibling-prefix path","id":"CVE-2026-48049"},"products":["arc"],"published":"2026-08-21","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-25","vendors":["Basekick-Labs"]},"summary":"Unauthenticated access to Arc database debug endpoints allows attackers to leak runtime state and cause denial of service via CPU exhaustion.","url":"https://insights.sbomify.com/CVE-2026-48050/"}
