CVE-2026-119576: ArcadeDB from 21.12.1 before 26.10.2 GraphQL Schema Replacement via Read-Only Query Endpoint
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: 0.21% (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 26.10.2.
Low priority for now. Upgrade to ArcadeData arcadedb 26.10.2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
ArcadeDB from 21.12.1 before 26.10.2 contains an authorization bypass vulnerability that allows users with only readRecord to replace the shared GraphQL schema via the read-only query endpoint. Attackers can send a GraphQL type definition with a crafted @sql directive to /api/v1/query/{database}, altering query results returned to other users including administrators.
