CVE-2026-101631: Oracle MySQL Router authentication bypass in HTTPS endpoint

CVE-2026-101631 · Severity: medium · CVSS 6.8 · Published 2026-10-20

MySQL Router is a lightweight middleware that routes database connections to MySQL servers. An unauthenticated attacker can exploit a difficult-to-exploit vulnerability in the HTTPS endpoint to create, delete, or modify critical data, or access all data stored in MySQL Router—but only if a legitimate user can be tricked into facilitating the attack. This could expose sensitive database information or enable unauthorized administrative actions.
