Description

Insufficient filtering of credentials in the _replicator database in Apache CouchDB 3.5.2 and below on all platforms allows an authenticated user to read replication credentials of other users’ replications, not just their own. Users are recommended to upgrade to version 3.5.3, which fixes this issue.
