CVE-2026-33194

SiYuan CVE-2026-33194 affects versions prior to 3.6.2. The vulnerability stems from an incomplete denylist in the IsSensitivePath() function (kernel/util/path.go) which was expanded but still does not block several Linux directories such as /opt, /usr, /home, /mnt, and /media. The affected endpoi...

CVE-2026-32747

SiYuan is a personal knowledge management system. In versions 3.6.0 and below, the globalCopyFiles API eads 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 c...

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal through the IsSensitivePathp string bool path check in kernel/util/path.go. An attacker can copy and then read files outside the workspace, including data under /opt, /usr, and others, by abusing the globalCopyFiles...

SiYuan has an Incomplete Fix for IsSensitivePath Denylist Allows File Read from /opt, /usr, /home (GHSA-h5vh-m7fg-w5h6 Bypass)

Summary The IsSensitivePath function in kernel/util/path.go uses a denylist approach that was recently expanded GHSA-h5vh-m7fg-w5h6, commit 9914fd1 but remains incomplete. Multiple security-relevant Linux directories are not blocked, including /opt application data, /usr local configs/binaries,...
