AI risk analysis

Summary: Lektor 3.3.14 and 3.4.0b15 are vulnerable to cross-site request forgery, allowing unauthenticated attackers to perform state-changing actions via cross-origin requests without proper CSRF protection.
Exploitability: Exploitation is relatively easy as it requires sending cross-origin requests from a malicious web page, which can be automated with minimal effort.
Blast radius: If exploited, attackers can write arbitrary files, delete pages, and trigger deployment publication, leading to significant data loss and system compromise.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to Lektor 3.3.15 or later.

NVD description

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.
