Privilege escalation in Presto

Affected

This affects Presto server installations. This does NOT affect clients such as the CLI or JDBC driver.

Impact

Authenticated users can bypass authorization checks by directly accessing internal APIs. This impacts Presto server installations with secure internal communication configured.

This does not affect installations that have not configured secure internal communication, as these installations are inherently insecure.

Patches

This issue has been fixed starting with PrestoSQL version 337.

Workarounds

This issue can be mitigated by blocking network access to internal APIs on the coordinator and workers.

References

See the Presto documentation for Secure Internal Communication.
