      <title>CVE-2023-28111 — Discourse vulnerable to SSRF protection bypass possible with IPv4-mapped IPv6 addresses</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2023-28111</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; discourse&lt;/p&gt;
&lt;p&gt;Discourse is an open-source discussion platform. Prior to version 3.1.0.beta3 of the `beta` and `tests-passed` branches, attackers are able to bypass Discourse&amp;#39;s server-side request forgery (SSRF) protection for private IPv4 addresses by using a IPv4-mapped IPv6 address. The issue is patched in the latest beta and tests-passed version of Discourse. version 3.1.0.beta3 of the `beta` and `tests-passed` branches. There are no known workarounds.&lt;/p&gt;</description>
