Apache Software Foundation Apache Juneau
Apache Juneau: Sensitive request headers logged in cleartext by the default request logger on server errors
CVSS 4.0
10.0Critical
Official description
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.
