AI-suggested
Upgrade forge to version 1.4.3 or later, where the issue is fixed by proper enforcement of the nameConstraints extension. No other mitigations are indicated or required.
Description
A vulnerability in digitalbazaar's forge library prior to version 1.4.3 allows improper validation of the X.509 nameConstraints extension during certificate chain verification. This flaw permits a name-constrained certificate authority with a non-critical extension to issue certificates outside permitted namespaces, potentially enabling impersonation of unauthorized names. The issue is fixed in version 1.4.3.
