What happened

Insufficiently Protected Credentials vulnerability in Apache Juneau.

The Apache Juneau RestClient followed HTTP redirects while keeping credential headers from the original request, so a server that redirected the client to a different host or port, or from HTTPS to HTTP, could receive headers such as Authorization, Cookie, Proxy-Authorization and X-API-Key.

This issue affects Apache Juneau: through 9.2.0.

Users are recommended to upgrade to version 9.2.1, which fixes the issue. The fix applies to HTTP clients created by the RestClient builder; applications that supply their own HttpClient must disable automatic redirects or strip credential headers on cross-origin redirects themselves.

About this data

This record was ingested from a data source. Retrieved: Nov 5, 2026, 16:35 UTC. Ingestion is not an independent editorial investigation.

NVD status: Deferred. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
