{"id":"CVE-2026-93595","summary":"ArcadeDB before 26.9.1 ACL Bypass via query_database Tool","details":"ArcadeDB before 26.9.1 contains an access control bypass vulnerability in the query_database tool exposed through the AI chat endpoints. The tool executes queries without binding the authenticated principal to DatabaseContext, causing per-type and per-bucket ACL checks to silently no-op and allowing authenticated users to read data they are explicitly denied at the per-type level. Attackers can prompt the AI assistant to execute queries against restricted types or buckets to retrieve sensitive data that would be rejected through normal query endpoints.","aliases":["GHSA-chrr-vr3p-crcc"],"modified":"2026-09-20T11:47:30.012940434Z","published":"2026-09-18T13:20:07.472Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93595.json"},"references":[{"type":"ADVISORY","url":"https://github.com/ArcadeData/arcadedb/security/advisories/GHSA-chrr-vr3p-crcc"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93595.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93595"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/arcadedb-before-26.9.1-acl-bypass-via-query-database-tool"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/arcadedata/arcadedb","events":[{"introduced":"0"},{"fixed":"b6a92623554bb332d7564de19fbd9fdbc2d1d45e"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"26.9.1"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"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-2026-93595.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:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
