v22.0.4Storage & Data
Feb 27, 2026

Security-focused release addressing two critical CVEs related to backup MANIFEST file vulnerabilities that could allow arbitrary command execution and path traversal attacks.

  • securityImmediate upgrade required for CVE-2026-27965 and CVE-2026-27969

    Two critical CVEs allow attackers with backup storage write access to execute arbitrary commands and perform path traversal attacks. Upgrade immediately to v22.0.4 and review backup storage access controls to ensure only trusted entities have write permissions.

  • breakingUpdate VTTablet configuration if using MANIFEST-based decompressors

    External decompressor commands from MANIFEST files are ignored by default. If your restore process relies on this behavior, add the --external-decompressor-use-manifest flag to your VTTablet configuration, but understand this reintroduces security risks.

  • securityAudit and secure backup storage access

    Since these vulnerabilities require write access to backup storage, review who has write permissions to your backup locations. Implement proper access controls and consider using immutable backup storage where possible to prevent tampering.
