CVE-2026-32281

7.5 highEPSS 0.4%

High (7.5) in golang go. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in stdlib 1.25.9, 1.26.2.

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.
