CVE-2026-46860

Unauthenticated HTTP Access Allows Full Compromise of Oracle MySQL Router

Published Jun 16, 2026 CVSS 3.1 · 9.8 Critical EPSS < 1% KEV · Not listed

Description

Vulnerability in the MySQL Router product of Oracle MySQL (component: Router: General). Supported versions that are affected are 9.0.0-9.7.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise MySQL Router. Successful attacks of this vulnerability can result in takeover of MySQL Router. CVSS 3.1 Base Score 9.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

Analysis

Technical impact

A flaw in the HTTP interface of Oracle MySQL Router allows an unauthenticated attacker with network access to compromise the router. Successful exploitation can lead to full takeover of the routing service, affecting confidentiality, integrity, and availability of the router itself and potentially the database connections it forwards.

Affected Systems

Oracle MySQL Router versions 9.0.0 through 9.7.0 are affected. The vulnerability applies to the general Router component and is present in all builds within that range.

Risk and Exploitability

The CVSS 3.1 base score of 9.8 indicates critical severity. The EPSS score is below 1%, implying that exploitation is currently uncommon, but the zero‑authentication requirement and direct HTTP access mean an attacker can exploit it with only network reach to the router’s HTTP port. The vulnerability is not listed in CISA KEV, but its high impact warrants rapid action.

OpenCVE Recommended Actions

Apply any available Oracle patch for MySQL Router as identified in the security advisory.
If a patch cannot be applied immediately, disable or restrict the HTTP management interface on the router to prevent unauthenticated access.
Use firewall rules or network segmentation to block external traffic to the router’s HTTP port when the interface is not required for your environment.
