Description OSIDB Bzimport 2025-04-10 12:30:38 UTC

Hostname verification issue that causes the trust store to trust all certificates. By setting the verification policy to 'ALL' not only the hostname check is skipped, but also the trust store certificate verification, which is an unintended side effect.
