      <title>CVE-2026-100556 — OpenClaw before 2026.8.1 Authentication Bypass via Session Reset</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-100556</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; OpenClaw&lt;/p&gt;
&lt;p&gt;OpenClaw (npm package openclaw) versions &amp;gt;= 2026.5.2 and &amp;lt; 2026.8.1 contain an incorrect authorization vulnerability in WhatsApp group handling. A group sender who is admitted for ordinary messages but denied by commands.allowFrom or owner command authorization can issue the /new &amp;lt;model&amp;gt; command to reset the shared group session and persist a provider and model override. This allows a command-denied group member to select a provider and model already permitted by the operator for subsequent turns in the shared group session, potentially changing provider routing, cost, data flow, or availability. It does not allow adding a new provider or host command execution. The issue is fixed in version 2026.8.1.&lt;/p&gt;</description>
