# Patch Next advisory brief: CVE-2023-22102

Advisory: MySQL Connectors takeover vulnerability
IDs: CVE-2023-22102, GHSA-m6vm-37g8-gqvh
Record: https://patchnext.com/advisories/cve-2023-22102 (revision 1, source checked 26 Oct 2026, 16:34 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: com.mysql:mysql-connector-j 8.2.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven com.mysql:mysql-connector-j: affected < 8.2.0; fixed in 8.2.0
- Maven mysql:mysql-connector-java: affected <= 8.0.33

## Suggested inspection (read-only)
- Maven com.mysql:mysql-connector-j: check the installed version with your package manager.
- Maven mysql:mysql-connector-java: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on com.mysql:mysql-connector-j, mysql:mysql-connector-java.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
