{"id":"CVE-2026-93595","state":"PUBLISHED","title":"ArcadeDB before 26.9.1 ACL Bypass via query_database Tool","description":"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.","publishedAt":"2026-09-18T13:20:07.472Z","updatedAt":"2026-09-21T20:52:08.205Z","severity":{"score":7.1,"label":"High","version":"4.0","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","source":"VulnCheck"},"assigner":"VulnCheck","products":["ArcadeData arcadedb"],"affected":[{"vendor":"ArcadeData","product":"arcadedb","packageURL":"pkg:maven/com.arcadedb/arcadedb-server","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"26.9.1","versionType":"semver"},{"version":"26.9.1","status":"unaffected","versionType":"semver"}]}],"references":["https://github.com/ArcadeData/arcadedb/security/advisories/GHSA-chrr-vr3p-crcc","https://www.vulncheck.com/advisories/arcadedb-before-26.9.1-acl-bypass-via-query-database-tool"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:13:34.582Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/93xxx/CVE-2026-93595.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-93595","state":"PUBLISHED","datePublished":"2026-09-18T13:20:07.472Z","dateUpdated":"2026-09-21T20:52:08.205Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-09-18T10:59:45.138Z"},"containers":{"cna":{"title":"ArcadeDB before 26.9.1 ACL Bypass via query_database Tool","descriptions":[{"lang":"en","value":"ArcadeDB before 26.9.1 contains an access control bypass vulnerability in the query_database tool exposed through the AI chat endpoints.
