What is CVE-2026-76223?
CVE-2026-76223 is a high-severity missing authorization vulnerability in ArcadeData arcadedb, published on 19 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
ArcadeDB (com.arcadedb) versions 26.7.3 and earlier fail to enforce the UPDATE_SCHEMA permission check when a DEFINE FUNCTION statement targets an already-existing function library. A user with only database access can add or overwrite SQL or Cypher functions in an existing library and persist the change, enabling tampering with admin-defined function logic. The issue is fixed in 26.8.1. (JavaScript functions still trigger the UPDATE_SECURITY check and are not affected.)
Weakness: CWE-862
