{
    "lastseen": "",
    "description": "SiYuan is an open-source personal knowledge management system. Prior to 3.7.0, the patch for CVE-2026-41894 (\"Path Traversal via Double URL Encoding\") sanitized the /export/ route but the identical root cause remains in the /assets/*path route. In publish mode (anonymous read-only HTTP endpoint, default port 6808), an unauthenticated remote attacker can read arbitrary files inside WorkspaceDir \u2014 including conf/conf.json (which contains the AccessAuthCode SHA256 hash, API token, and sync keys), temp/siyuan.db, temp/blocktree.db, and siyuan.log \u2014 by double-URL-encoding .. segments. This vulnerability is fixed in 3.7.0.",
