CVE-2026-73116

Critical

Description

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.
