CVE-2026-65831Network attack vectorHinoki check available

Host file read via polyglot sandbox escape

Published Sep 15, 2026 · Updated Sep 15, 2026

Incorrect authorization in ArcadeDB Server before 26.7.1 allows remote authenticated users with reader access to read arbitrary host files. PolyglotQueryEngine omits administrator checks for JavaScript commands, while GraalPolyglotEngine lets scripts reflect from the bound database object to load arbitrary host classes. Reader access to one database and access to the HTTP command endpoint are required; process creation remains blocked, so confirmed impact is host-file disclosure.
