What is CVE-2026-90798?

A critical flaw in Apache CouchDB versions 3.5.2 and earlier permits an attacker to cause a denial of service through the creation of an infinite HTTP redirect loop. This design defect, stemming from a missing circuit-breaker in the replication mechanism, allows the owner of either the source or target of replication to disrupt service. Users are strongly urged to upgrade to Apache CouchDB version 3.5.3 or later to mitigate this issue.

Affected Version(s)

Apache CouchDB 0 < 3.5.3
