AI description
CVE-2026-73100 is an information disclosure vulnerability affecting Apache Juneau, specifically within its default REST server call logger. The issue arises when an incoming request ends in a server error. In these instances, the logger records the request headers without redacting sensitive information, writing them in cleartext directly to the application log. This flaw exposes sensitive headers, such as Authorization, Cookie, Proxy-Authorization, and X-API-Key, to anyone with read access to the application logs. The vulnerability affects Apache Juneau versions up to and including 9.2.0. To resolve the issue, users are advised to upgrade to version 9.2.1, which introduces proper redaction for these headers.
