      <title>CVE-2026-123804 — SuperTokens Core: A session created concurrently with account unlink survives the unlink</title>
      <link>https://db.gcve.eu/vuln/cve-2026-123804</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; supertokens-core&lt;/p&gt;
&lt;p&gt;SuperTokens Core is an open source authentication server. From 7.0.0 until 11.0.9, 11.1.4, 11.2.4, 11.3.8, 11.4.8, 12.0.11, 12.1.2, 12.2.1, and 12.3.1, createNewSession can resolve a primary user before unlinkAccounts detaches a login method and then insert the session after unlink has enumerated and revoked the existing sessions. A user who controls the linked login method can exploit this race to retain a signed, database-backed, refreshable session as the former primary identity after that method is unlinked; the session persists until expiry or explicit revocation. This issue is fixed in versions 11.0.9, 11.1.4, 11.2.4, 11.3.8, 11.4.8, 12.0.11, 12.1.2, 12.2.1, and 12.3.1.&lt;/p&gt;</description>
