A user with only database access can add or overwrite SQL or Cypher functions in an existing library and persist the change, enabling tampering with admin-defined function logic. The issue is fixed in 26.8.1. (JavaScript functions still trigger the UPDATE_SECURITY check and are not affected.)","published":"2026-08-19T14:17:48.740","modified":"2026-08-19T14:17:48.740","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/ArcadeData/arcadedb/security/advisories/GHSA-rv64-62hr-wv2p"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/arcadedb-before-permission-bypass-via-define-function"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-19T14:17:48.740"}}
