Metabase Enterprise Edition allows cached questions to leak data to impersonated users

Metabase Enterprise Edition is the enterprise version of Metabase business intelligence and data analytics software. Starting in version 1.47.0 and prior to versions 1.50.36, 1.51.14, 1.52.11, and 1.53.2 of Metabase Enterprise Edition, users with impersonation permissions may be able to see results of cached questions, even if their permissions don’t allow them to see the data. If some user runs a question which gets cached, and then an impersonated user runs that question, then the impersonated user sees the same results as the previous user. These cached results may include data the impersonated user should not have access to. This vulnerability only impacts the Enterprise Edition of Metabase and not the Open Source Edition. Versions 1.53.2, 1.52.11, 1.51.14, and 1.50.36 contains a patch. Versions on the 1.49.X, 1.48.X, and 1.47.X branches are vulnerable but do not have a patch available, so users should upgrade to a major version with an available fix. Disabling question caching is a workaround for this issue.
