      <title>CVE-2026-55485 — Piccolo Admin: Privilege escalation - admin to superuser via session-token disclosure in GET /api/tables/sessions/.</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-55485</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; piccolo-orm piccolo_admin&lt;/p&gt;
&lt;p&gt;Piccolo Admin is an admin interface and content management system for Python, built on top of Piccolo. Prior to 1.14.0, piccolo_admin/endpoints.py uses superuser_validators to block PUT, PATCH, DELETE, and POST requests by non-superusers but permits GET requests to configured user and session tables, while piccolo_api/session_auth/tables.py exposes SessionsBase.token because the token column is not secret. In deployments that add the Sessions and User tables to create_admin, a non-superuser administrator can call GET /api/tables/sessions/, obtain another user&amp;#39;s live session token, replay it as the Cookie id value to impersonate a superuser, and permanently set superuser to true on the attacker&amp;#39;s own row. This issue is fixed in version 1.14.0.&lt;/p&gt;</description>
