CVE-2026-27965
CriticalSummary
Vitess to system klastrowania baz danych dla poziomego skalowania MySQL. W wersjach przed 23.0.3 i 22.0.4, każda osoba z dostępem do lokalizacji przechowywania kopii zapasowych (np. bucket S3) może manipulować plikami manifestu kopii zapasowej, co pozwala na wykonanie dowolnego kodu podczas przywracania tej kopii zapasowej.
Risk Assessment
Atakujący może uzyskać nieautoryzowany dostęp do środowiska produkcyjnego, co umożliwia dostęp do informacji oraz uruchamianie dodatkowych poleceń. To stwarza poważne zagrożenie dla bezpieczeństwa danych organizacji.
Recommendation
Zaleca się aktualizację do wersji 23.0.3 lub 22.0.4, które zawierają poprawki. Dodatkowo, można zastosować obejścia, takie jak określenie komendy dekompresora w flagach `--external-decompressor` dla `vttablet` i `vtbackup`.

Original NVD description (English source)
Vitess is a database clustering system for horizontal scaling of MySQL. Prior to versions 23.0.3 and 22.0.4, anyone with read/write access to the backup storage location (e.g. an S3 bucket) can manipulate backup manifest files so that arbitrary code is later executed when that backup is restored. This can be used to provide that attacker with unintended/unauthorized access to the production deployment environment — allowing them to access information available in that environment as well as run any additional arbitrary commands there. Versions 23.0.3 and 22.0.4 contain a patch. Some workarounds are available. Those who intended to use an external decompressor then can always specify that decompressor command in the `--external-decompressor` flag value for `vttablet` and `vtbackup`. That then overrides any value specified in the manifest file. Those who did not intend to use an external decompressor, nor an internal one, can specify a value such as `cat` or `tee` in the `--external-deco
