Technical details
A Cross-Site Request Forgery (CSRF) vulnerability exists in Apache Zeppelin versions 0.6.0 through 0.12.0. The root cause is a permissive default CORS configuration that allowed cross-origin state-changing requests (POST, PUT, DELETE, PATCH) and accepted 'text/plain' request bodies, which bypasses standard browser CORS preflight protections. An attacker can exploit this by luring an authenticated user to a malicious site that sends forged requests to the Zeppelin REST or WebSocket endpoints. Successful exploitation allows the attacker to perform state-changing actions with the victim's privileges. The issue is resolved in version 0.12.1 by tightening origin validation, restricting accepted Content-Types, and setting 'SameSite=Lax' for session cookies.
