Upstream source description

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.
