CVE-2026-41928Network attack vector

Cron-key disclosure via echoed callback URL

Published May 7, 2026 · Updated May 7, 2026

Information disclosure in Vvveb before 1.0.8.2 allows remote attackers to retrieve the application's secret cron key. The Cron::call() method in app/controller/cron.php reads app.cronkey and echoes a generated cron/index callback URL containing the key. Unauthenticated HTTP access exposes the key, which permits scheduled tasks to be triggered outside their intended schedule.
