description

Apache Juneau REST server components through 9.2.0 may write sensitive request headers to application logs when requests end in server errors. A client that can trigger such errors may cause credentials or session data to be exposed to users who can read those logs.

mitigation

Upgrade org.apache.juneau:juneau-rest-server and org.apache.juneau:juneau-rest-common to version 9.2.1. Restrict access to application logs while the upgrade is being applied.

fixed in 9.2.1
