Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-47735 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 0.0.0-20260520141557-91bdc29d1a02\n- github.com/basekick-labs/arc (Go): affected all versions; fixed in 0.0.0-20260520141557-91bdc29d1a02\n- github.com/basekick-labs/arc (Go): affected all versions; fixed in 0.0.0-20260520141557-91bdc29d1a02\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-2026-47735/ (Markdown: https://insights.sbomify.com/CVE-2026-47735/index.md)","id":"CVE-2026-47735","markdown":"https://insights.sbomify.com/CVE-2026-47735/index.md","name":"CVE-2026-47735","record":{"aliases":["GHSA-p2j4-c4g6-rpf5","GO-2026-5523"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Arc time-series database","requires_auth":"low_privilege","summary":"Authenticated users can read arbitrary local files by bypassing SQL validation and RBAC checks using unblocked DuckDB I/O functions.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"},{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Arc is an open, SQL-native time-series database for telemetry. Prior to version 26.06.1, Arc's user-SQL validator (`internal/api/query.go:ValidateSQLRequest`) blocked only `read_parquet(` and `arc_partition_agg(` via regex denylist. The broader DuckDB I/O function family — `read_csv_auto`, `read_csv`, `read_json`, `read_json_auto`, `read_text`, `read_blob`, `glob`, `parquet_metadata`, `parquet_schema`, `read_xlsx`, etc. — was not blocked. RBAC table-reference extraction inspected only `FROM`/`JOIN` clauses, so scalar table functions in the `SELECT` list slipped past both layers. This is fixed in 2026.06.1 via a structural sandbox at the DuckDB layer. After lockdown, DuckDB refuses to open any file outside the allowlist and refuses further `INSTALL`/`LOAD`. Already-loaded extensions remain callable. Some workarounds are available. Restrict API access to known-trusted networks via firewall rules or, as a temporary mitigation, add `read_csv*`/`read_json*`/`glob` etc. to `dangerousSQLPattern` in `internal/api/query.go`.","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 has an authenticated arbitrary local-file read via DuckDB I/O functions that bypasses RBAC table-level checks","id":"CVE-2026-47735","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":3,"n_references":4,"next":{"headline":"Puma PROXY Protocol v1 Parser Allows Remote Memory Exhaustion","id":"CVE-2026-47736"},"packages":[{"ecosystem":"Go","fixed":["0.0.0-20260520141557-91bdc29d1a02"],"introduced":["0"],"last_affected":[],"package":"github.com/basekick-labs/arc","purl":null,"source":"GHSA-p2j4-c4g6-rpf5"},{"ecosystem":"Go","fixed":["0.0.0-20260520141557-91bdc29d1a02"],"introduced":["0"],"last_affected":[],"package":"github.com/basekick-labs/arc","purl":"pkg:golang/github.com/basekick-labs/arc","source":"GHSA-p2j4-c4g6-rpf5"},{"ecosystem":"Go","fixed":["0.0.0-20260520141557-91bdc29d1a02"],"introduced":["0"],"last_affected":[],"package":"github.com/basekick-labs/arc","purl":"pkg:golang/github.com/basekick-labs/arc","source":"GO-2026-5523"}],"prev":{"headline":"Dulwich has unbounded memory allocation in receive-pack from crafted thin packs","id":"CVE-2026-47734"},"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-25","vendors":["Basekick-Labs"]},"summary":"Authenticated users can read arbitrary local files by bypassing SQL validation and RBAC checks using unblocked DuckDB I/O functions.","url":"https://insights.sbomify.com/CVE-2026-47735/"}
