      <title>CVE-2026-100637 — SiYuan before v3.8.4 Path Traversal via checkoutRepo sessionID</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-100637</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; siyuan-note siyuan&lt;/p&gt;
&lt;p&gt;SiYuan versions before v3.8.4 contain a path traversal vulnerability in the checkoutRepo endpoint that allows authenticated administrators to write JSON files outside the workspace. Attackers can supply a sessionID parameter containing directory traversal sequences to overwrite arbitrary JSON files in pre-existing kernel-writable directories outside workspace boundaries.&lt;/p&gt;</description>
