Assigner: apache
Reserved: 13.09.2026 Published: 20.10.2026 Updated: 20.10.2026

A missing circuit-breaker in the replicator in Apache CouchDB 3.5.2 and below on all platforms allows the owner of a replication source or target to cause a denial of service via creating an infinite HTTP redirect loop.

Users are recommended to upgrade to version 3.5.3, which fixes this issue.
