      <title>CVE-2026-7646 — Langflow is affected by security vulnerabilities in Model Context Protocol features</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-7646</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; IBM Langflow OSS&lt;/p&gt;
&lt;p&gt;IBM Langflow OSS 1.0.0 through 1.10.3 allows users to read arbitrary files from the server filesystem, including other users&amp;#39; uploaded documents, the JWT signing secret, the SQLite database, and process environment variables, by sending a crafted MCP `resources/read` request with a URL-encoded path traversal sequence in the filename.&lt;/p&gt;</description>
