July 6, 2020

This page lists additions and changes in v19.2.9 since v19.2.8.

  • For a comprehensive summary of features in v19.2, see the v19.2 GA release notes.
  • To upgrade to the latest production release of CockroachDB, see this article.

A denial-of-service (DoS) vulnerability is present in CockroachDB v19.2.0 - v19.2.11 due to a bug in protobuf. This is resolved in CockroachDB v19.2.12 and later releases. When upgrading is not an option, users should audit their network configuration to verify that the CockroachDB HTTP port is not available to untrusted clients. We recommend blocking the HTTP port behind a firewall.

For more information, including other affected versions, see Technical Advisory 58932.


Cockroach Labs has discovered a bug relating to incremental backups, for CockroachDB v19.2.0 - v19.2.12. If a backup coincides with an in-progress index creation (backfill), RESTORE, or IMPORT, it is possible that a subsequent incremental backup will not include all of the indexed, restored or imported data.

Users are advised to upgrade to v20.1.15 or v20.2.8 or later, which includes resolutions.

For more information, including other affected versions, see Technical Advisory 63162.

General changes

Bug fixes

  • Fixed a bug that occurred during incremental backups with revision history on a database (or full cluster) when a table in the database being backed up was dropped. When other tables were later created, dropped, or altered, future incremental backups would return an error. #50208
  • Fixed a bug in TRUNCATE that could leave tables in a state where they could not be renamed. #50714 #50756#50756]
