{"id":"CVE-2026-33194","aliases":["GHSA-vm69-h85x-8p85","GO-2026-4766"],"url":"https://o3.security/vulnerability/CVE-2026-33194","summary":"SiYuan has an Incomplete Fix for IsSensitivePath Denylist Allows File Read from /opt, /usr, /home","details":"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.","published":"2026-03-20T22:30:33.141Z","modified":"2026-08-12T03:51:47.977219717Z","cvss":{"score":6.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N"},"epss":{"score":0.00489,"percentile":0.40945,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/siyuan-note/siyuan/kernel","fixedVersion":"3.6.2"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33194.json"},{"type":"ADVISORY","url":"https://github.com/siyuan-note/siyuan/security/advisories/GHSA-vm69-h85x-8p85"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33194"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:47.977219717Z"}}
