Doc Text:
A flaw was found in Cockpit CMS. The application disables Transport Layer Security (TLS) certificate verification when making background requests to restart web workers. An attacker in a position to intercept network traffic could exploit this flaw by presenting an arbitrary certificate, allowing them to capture sensitive worker authentication tokens and trigger background worker tasks.

Description OSIDB Bzimport 2026-10-04 17:21:26 UTC
Cockpit CMS 2.12.0 before 2.14.1 disables TLS certificate verification in the cron.php web worker restart request, allowing network attackers to capture the worker token. Man-in-the-middle attackers on the outbound path to site_url can present any certificate to steal the worker/web/token value and start the web worker.
