      <title>CVE-2026-101878 — Bitwarden Server 2025.6.0 &lt; 2025.6.0 Authentication Bypass via SSO Identifier Truncation</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-101878</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; bitwarden server&lt;/p&gt;
&lt;p&gt;Bitwarden Server 2025.6.0 before 2026.5.0 declares the @ExternalId parameter of the User_ReadBySsoUserOrganizationIdExternalId stored procedure as NVARCHAR(50) while the column it queries stores NVARCHAR(300), silently truncating the SSO login identifier on SQL Server deployments and allowing a user whose identity-provider identifier begins with another organization member&amp;#39;s full 50-character identifier to authenticate as that member and obtain a victim-scoped access token.&lt;/p&gt;</description>
