What is CVE-2026-27969?

Vitess, a database clustering system designed for the horizontal scaling of MySQL, is vulnerable due to improper handling of backup manifest files. If a user has read/write access to the backup storage location, such as an S3 bucket, they can manipulate these manifest files. This could allow them to redirect files from the manifest to any accessible location during the restore process. As a result, attackers can gain unauthorized access to the production deployment environment, potentially compromising sensitive information and executing arbitrary commands. To mitigate this issue, users are advised to upgrade to Vitess versions 23.0.3 or 22.0.4 where the vulnerability has been patched.
