SiYuan 3.8.7 through 3.8.8 fails to normalize Windows GLOBALROOT device-namespace aliases, bypassing the IsSensitivePath denylist. Attackers can invoke importStdMd with a GLOBALROOT-prefixed path to copy the API token and TLS private key into the publicly served assets directory...

CVE-2026-116171 SiYuan 3.5.4 before 3.8.7 Sensitive Path Bypass via Windows Extended-Length Prefix

SiYuan 3.5.4 before 3.8.7 on Windows contains a sensitive-path denylist bypass in IsSensitivePath because the Windows extended-length prefix \?\ survives filepath.Clean and matches no forbidden prefix. Authenticated API callers can prepend the prefix to localPath in /api/import/importStdMd to cop...
