CVE-2026-73099 Details
Description
Cross-Site Request Forgery (CSRF) vulnerability in Apache Juneau. The REST server accepts a "content" query parameter that replaces the request body, and this is enabled by default on every HTTP method, including GET. A cross-site link can therefore deliver an attacker-chosen request body to an endpoint without a CORS preflight, defeating protections that rely on the HTTP method or content type instead of an anti-CSRF token. This issue affects Apache Juneau: through 9.2.0. Users are recommended to upgrade to version 9.2.1, which fixes the issue. Applications that do not use the content parameter can also set disableContentParam to true.
A Cross-Site Request Forgery (CSRF) vulnerability exists in Apache Juneau REST server versions through 9.2.0. The vulnerability arises because the server accepts a 'content' query parameter that replaces the request body, a feature enabled by default on all HTTP methods, including GET. This allows an attacker to send a crafted request body to an endpoint without triggering a CORS preflight, bypassing protections that depend on the HTTP method or content type, rather than an anti-CSRF token.
Users are advised to upgrade to Apache Juneau version 9.2.1, which addresses this vulnerability. For applications that do not utilize the content parameter, it is recommended to set 'disableContentParam' to true.
