CVE-2026-73100
Published:November 05, 2026
Updated:November 09, 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.
