CVE-2026-114058: ArcadeDB from 26.2.1 before 26.10.1 Missing Authorization via Bolt Protocol

MediumCVSS 5.3 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.29% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: ArcadeData arcadedb 26.10.1.

Low priority for now. Upgrade to ArcadeData arcadedb 26.10.1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
