      <title>CVE-2026-93602 — rustls-webpki before 0.103.10 CRL Revocation Check Bypass</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-93602</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; rustls webpki&lt;/p&gt;
&lt;p&gt;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&amp;#39;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.&lt;/p&gt;</description>
