CVE-2026-59832Public exploitNetwork attack vector

Authenticated file disclosure via unconfined snippets path

Published Jul 9, 2026 · Updated Jul 9, 2026

Path traversal in SiYuan before 3.7.1 allows remote authenticated users to read workspace secrets and the document database. The serveSnippets handler joins the single-decoded /snippets/ path to the snippets directory and serves the result without enforcing subpath containment or blocking sensitive paths. Any authenticated non-admin account can traverse to conf/conf.json for API and access secrets or to temp/siyuan.db for note content, while file permissions bound host-file access.
