CVE-2026-32747: SiYuan globalCopyFiles: incomplete sensitive path blocklist allows reading /proc and Docker secrets

March 16, 2026

POST /api/file/globalCopyFiles reads source files using filepath.Abs() with no workspace boundary check, relying solely on util.IsSensitivePath() whose blocklist omits /proc/, /run/secrets/, and home directory dotfiles. An admin can copy /proc/1/environ or Docker secrets into the workspace and read them via the standard file API.
