      <title>CVE-2026-55210 — Joplin: SAML SSO account takeover via email-based account linking (missing is_external check in ssoLogin)</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-55210</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; laurent22 joplin&lt;/p&gt;
&lt;p&gt;Joplin is an open source note-taking and to-do application that organises notes and lists into notebooks. Prior to 3.7.2, Joplin Server&amp;#39;s UserModel.ssoLogin() returns an existing account matched by an IdP-asserted email without checking the account&amp;#39;s is_external flag. In deployments using mixed local and SAML authentication, an attacker whose IdP session can assert a local user&amp;#39;s email can pass POST /api/saml, receive a session for that local account, and access or modify the victim&amp;#39;s notes, files, and settings without knowing the local password. This issue is fixed in version 3.7.2.&lt;/p&gt;</description>
