      <title>CVE-2022-3916 — Keycloak: session takeover with oidc offline refreshtokens</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2022-3916</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Red Hat Single Sign-On 7, Red Hat Single Sign-On 7.6.1, Red Hat Single Sign-On 7.6 for RHEL 7, Red Hat Single Sign-On 7.6 for RHEL 8, Red Hat Single Sign-On 7.6 for RHEL 9, Red Hat RHEL-8 based Middleware Containers&lt;/p&gt;
&lt;p&gt;A flaw was found in the offline_access scope in Keycloak. This issue would affect users of shared computers more (especially if cookies are not cleared), due to a lack of root session validation, and the reuse of session ids across root and user authentication sessions. This enables an attacker to resolve a user session attached to a previously authenticated user; when utilizing the refresh token, they will be issued a token for the original user.&lt;/p&gt;</description>
