CVSS 3.1
6.8 mediumCVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:NCVE-2026-33194
Medium (6.8) in b3log siyuan. EPSS 0.5% chance of exploitation in the next 30 days. Fixed in github.com/siyuan-note/siyuan/kernel 3.6.2.
SiYuan is a personal knowledge management system. Prior to version 3.6.2, 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), `/home` (other users), `/mnt` and `/media` (mounted volumes). The `globalCopyFiles` and `importStdMd` endpoints rely on `IsSensitivePath` as their primary defense against reading files outside the workspace. Version 3.6.2 contains an updated fix.
