CVE-2026-72799: Missing Authorization in siyuan-note siyuan
SiYuan versions before 3.7.4 (specifically versions up to 3.7.2) contain a vulnerability where publish-access filters are not enforced on certain filetree path-resolution endpoints. This allows unauthenticated users or any publish reader token to enumerate the entire private document tree, including notebook names, folder structures, and document titles. The exposure includes documents marked as hidden, password-protected, or publish-forbidden.
AI Analysis
Technical Summary
CVE-2026-72799 describes a missing authorization vulnerability in SiYuan note-taking software versions up to 3.7.2. The flaw affects five filetree path-resolution endpoints (getFullHPathByID, getHPathByID, getPathByID, getIDsByHPath, and getHPathByPath) where publish-access filters are not enforced when Publish.Auth.Enable is false in publish mode. This allows unauthenticated or any publish reader token users to enumerate the complete private document tree, revealing notebook names, folder hierarchies, document titles, and resolving title paths to document IDs, including those documents that are hidden, password-protected, or marked as publish-forbidden.
Potential Impact
An attacker without authentication can map the entire private document tree structure, exposing sensitive metadata such as notebook names, folder hierarchies, and document titles. This includes documents intended to be hidden or protected, potentially leading to privacy breaches and information disclosure. However, the vulnerability does not indicate direct document content exposure or modification capabilities.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been documented at this time. Users should monitor vendor communications for updates and consider restricting access to publish mode or enabling Publish.Auth.Enable until a fix is available.
