      <title>CVE-2026-61644 — FastGPT: /api/core/chat/record/getCollectionQuote can disclose cross-tenant dataset text due to an unbound initialId lo…</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-61644</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; labring FastGPT&lt;/p&gt;
&lt;p&gt;FastGPT is a knowledge-based AI application platform. From 4.14.17 until 4.15.0-beta5, the POST /api/core/chat/record/getCollectionQuote endpoint authenticates the caller&amp;#39;s chat and collection context, but the initialId center-node lookup is not bound to that authorized context. A low-privileged tenant user can call the endpoint with valid attacker-owned appId, chatId, chatItemDataId, and collectionId values while supplying another tenant&amp;#39;s dataset data id as initialId, causing the response to include foreign dataset quote or full-text content. This issue is fixed in version 4.15.0-beta5.&lt;/p&gt;</description>
