CVE-2025-6224: Canonical Juju/utils

Medium severity, CVSS 6.5. EPSS: 0.2% chance of exploitation in the next 30 days.

Certificate generation in juju/utils using the cert.NewLeaf function could include private information. If this certificate were then transferred over the network in plaintext, an attacker listening on that network could sniff the certificate and trivially extract the private key from it.

Affected products

• Canonical Juju/utils: from 4.0.0, before 4.0.4 (fixed in 4.0.4)
