      <title>CVE-2026-82879 — DataEase before 2.10.26 Access Control Bypass via Share Tickets</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-82879</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; dataease&lt;/p&gt;
&lt;p&gt;DataEase before 2.10.26 contains multiple access control defects in the sharing link module. Tickets are not bound to the target share UUID, so a valid ticket issued for one share can be reused against another (ShareTicketManage.validateTicket / POST /de2api/share/proxyInfo). The POST /de2api/share/validate endpoint issues a LinkToken after password verification without requiring a ticket, bypassing the &amp;#39;ticket mandatory&amp;#39; policy. Additionally, the ticket create and delete endpoints (POST /de2api/ticket/saveTicket, POST /de2api/ticket/delTicket) lack share-ownership checks, allowing an authenticated user who knows another user&amp;#39;s ticket to modify, rebind, or delete it (denial of service), and GET /de2api/share/queryRelationByUserId/{uid} allows authenticated users to enumerate other users&amp;#39; share mappings.&lt;/p&gt;</description>
