Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-75843 exists.\n\nAffected product: ArcadeData arcadedb. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-75843/ (Markdown: https://insights.sbomify.com/CVE-2026-75843/index.md)","id":"CVE-2026-75843","markdown":"https://insights.sbomify.com/CVE-2026-75843/index.md","name":"CVE-2026-75843","record":{"aliases":["GHSA-p29f-345w-4qwf","GHSA-pgf7-648w-96c5"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"ArcadeDB database","requires_auth":"low_privilege","summary":"Authenticated users can escalate privileges to administrator by executing unrestricted JavaScript via gRPC transactions in ArcadeDB.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"ArcadeDB before 26.8.1 fails to bind the authenticated principal on the gRPC transaction executor thread in beginTransaction, allowing authenticated readers to execute JavaScript commands without scripting authorization checks.
