CVE-2026-93597: Server-Side Request Forgery (SSRF)

ArcadeDB versions before 26.9.1 fail to validate IPv6 transition addresses in the SSRF guard used by IMPORT DATABASE and server commands.

CVE-2026-93596: Missing Authorization

ArcadeDB before 26.9.1 com.arcadedb:arcadedb-engine = 26.8.1 fails to bind the authenticated principal onto the DatabaseAsyncTransaction async worker threads used by the parallel edge-connect phase of POST /api/v1/batch/database. Because those workers have no current user,...

CVE-2026-93594: Incorrect Authorization

ArcadeDB Maven artifact com.arcadedb:arcadedb-engine through 26.8.1 enforces its per-type/per-record access-control rules only in LocalBucket, keyed on file id. Query-execution paths that reach record data through LSM index files or the TimeSeries engine never invoke that permission check, so an...

CVE-2026-93598: Incomplete List of Disallowed Inputs

ArcadeDB Maven artifact com.arcadedb:arcadedb-engine through 26.8.1 contains an incomplete deny-list in the polyglot script sandbox: com.arcadedb.query.polyglot.HostClassLookupFilter.DENIED lists java.util.ResourceBundle as a bare class name, which is matched by exact equality and therefore does...

CVE-2026-93595: Missing Authorization

ArcadeDB before 26.9.1 contains an access control bypass vulnerability in the querydatabase 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 allowi...

CVE-2026-93593: Incorrect Authorization

ArcadeDB before 26.9.1 fails to enforce security-group types ACL entries for TimeSeries types because the ACL resolver builds permissions from bucket IDs, but TimeSeries types do not own normal record buckets. An authenticated low-privilege user can read or insert TimeSeries samples despite...
