      <title>CVE-2026-76223 — ArcadeDB before 26.8.1 Permission Bypass via DEFINE FUNCTION</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-76223</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; ArcadeData arcadedb&lt;/p&gt;
&lt;p&gt;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.)&lt;/p&gt;</description>
