CVE-2026-73100 PUBLISHED

Apache Juneau: Sensitive request headers logged in cleartext by the default request logger on server errors

Assigner: apache
Reserved: 10.08.2026 Published: 05.11.2026 Updated: 05.11.2026

Insertion of Sensitive Information into Log File vulnerability in Apache Juneau.

The default REST server call logger records request headers for requests that end in a server error, without redacting them. Any client able to cause a server error gets headers such as Authorization, Cookie, Proxy-Authorization and X-API-Key written in cleartext to the application log, exposing them to anyone who can read the logs.

This issue affects Apache Juneau: through 9.2.0.

Users are recommended to upgrade to version 9.2.1, which fixes the issue.
