- CWE-295
Description
Validating certificate chains which use policies is unexpectedly inefficient when certificates in the chain contain a very large number of policy mappings, possibly causing denial of service. This only affects validation of otherwise trusted certificate chains, issued by a root CA in the VerifyOptions.Roots CertPool, or in the system certificate pool.
Affected configurations
• golang go (< 1.25.9)
• golang go (>= 1.26.0 < 1.26.2)
