Lektor 3.3.14 and 3.4.0b15 contains a cross-site request forgery vulnerability in the admin API blueprint that allows unauthenticated attackers to perform state-changing actions by sending cross-origin requests without CSRF tokens, Origin/Referer validation, CORS configuration, or Host allowlisting. Attackers can exploit the newattachment, deleterecord, build, clean, and publish endpoints from a malicious web page to write arbitrary files, delete pages, wipe build output, trigger deployment publication, and via DNS rebinding reach read endpoints to disclose data.
