rustls-webpki before 0.103.10 CRL Revocation Check Bypass
CVE-2026-93602 is fixed in 7 products on 1 platform, first by DEBIAN-CVE-2026-93602, released September 19, 2026. It is not reported as exploited. Patch Radar priority: Routine.
rustls-webpki versions before 0.103.10 and 0.104.0-alpha.5 contain faulty CRL authority-matching logic that compares only the first distributionPoint against each CRL's IssuingDistributionPoint, ignoring additional distributionPoints. Attackers with a compromised trusted issuing authority can present revoked certificates that pass revocation checks under UnknownStatusPolicy::Allow, or cause incorrect errors under the default deny policy.
