{"id":"CVE-2026-76223","summary":"ArcadeDB before 26.8.1 Permission Bypass via DEFINE FUNCTION","details":"ArcadeDB (com.arcadedb) versions 26.7.3 and earlier fail to enforce the UPDATE_SCHEMA permission check when a DEFINE FUNCTION statement targets an already-existing function library. 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.)","aliases":["GHSA-rv64-62hr-wv2p"],"modified":"2026-08-21T03:30:07.943210962Z","published":"2026-08-19T14:02:06.401Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/76xxx/CVE-2026-76223.json"},"references":[{"type":"ADVISORY","url":"https://github.com/ArcadeData/arcadedb/security/advisories/GHSA-rv64-62hr-wv2p"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/76xxx/CVE-2026-76223.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-76223"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/arcadedb-before-permission-bypass-via-define-function"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/arcadedata/arcadedb","events":[{"introduced":"0"},{"fixed":"87bdc67f1f0331fa2d07e932a550064c118eae70"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"26.8.1"}],"source":"AFFECTED_FIELD"}}],"versions":["untagged-3026f5635164cd300b5b","26.7.2","26.7.1","26.6.1","26.5.1","26.4.2","26.3.2","26.3.1","26.2.1","26.1.1","25.12.1","25.11.1","25.10.1","25.9.1","25.8.1","25.7.1","25.6.1","25.4.1","25.3.2","25.3.1","25.2.1","25.1.1","24.11.2","24.11.1","24.10.1","24.6.1","24.5.1","24.4.1","24.2.1","24.1.1","23.12.2","23.12.1","23.11.1","23.10.1","23.9.1","23.7.1","23.6.1","23.5.1","23.4.1","23.3.1","23.2.1","23.1.2","23.1.1","22.12.1","22.11.1","22.10.1","22.9.1","22.8.1","22.6.1","22.2.1","22.1.3","22.1.2","21.12.1","21.11.1","21.10.2","21.10.1","21.9.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-76223.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:L/SC:N/SI:N/SA:N"}]}
