Prior to 26.7.1, a reader-role user can submit POST /api/v1/command/{database} with language: js because PolyglotQueryEngine.command, PolyglotQueryEngine.analyze, and PolyglotQueryEngine.registerFunctions do not enforce database-administrator authorization. GraalPolyglotEngine also permits scripts to bypass the allowedPackages whitelist by reflecting from the bound database object through database.getClass().getClassLoader().loadClass to arbitrary host classes. These cooperating defects allow a read-only database user to read arbitrary host files outside the database scope. Process creation is already blocked, so OS command execution is not confirmed. The issue is distinct from CVE-2026-44221, CVE-2026-54076, and CVE-2026-54077. This issue is fixed in version 26.7.1.","published":"2026-09-15T15:18:32.339Z","modified":"2026-09-15T15:41:15.121Z","cvss":{"score":7.7,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/ArcadeData/arcadedb/commit/8ca396c07e471a0b97fee075eeb956b5e24a23be","label":"ArcadeData/arcadedb@8ca396c"},"references":[{"type":"WEB","url":"https://github.com/ArcadeData/arcadedb/security/advisories/GHSA-48qw-824m-86pr"},{"type":"WEB","url":"https://github.com/ArcadeData/arcadedb/commit/8ca396c07e471a0b97fee075eeb956b5e24a23be"},{"type":"WEB","url":"https://github.com/ArcadeData/arcadedb/releases/tag/26.7.1"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-15T15:41:15.121Z"}}
