ArcadeDB from 26.2.1 before 26.10.1 Missing Authorization via Bolt Protocol

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

ArcadeDB from 26.2.1 before 26.10.1 contains a missing authorization vulnerability in the Bolt protocol handler that lets authenticated users read other databases' schema metadata. Attackers with credentials for one database can set the db field in RUN or BEGIN messages and call db.labels() or SHOW INDEXES to enumerate unauthorized schemas.
