      <title>CVE-2026-89136 — Client accepts unsolicited RawPublicKey server certificate type</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-89136</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; wolfSSL&lt;/p&gt;
&lt;p&gt;When using RPK (Raw Public Key), the client side of a TLS 1.2, 1.3 and DTLS 1.2 connection could accept an unsolicited server_cert_type=RawPublicKey which allowed a malicious or misbehaving server to bypass authentication. RPK is off by default and only enabled in --enable-rpk OR --enable-all OR --enable-distro AKA HAVE_RPK builds.&lt;/p&gt;</description>
