CVE-2026-68587 Details
Description
SiYuan versions before v3.7.3 contain an information disclosure vulnerability in the getHeadingDeleteTransaction, getHeadingLevelTransaction, and getHeadingInsertTransaction endpoints that return rendered block DOM without publish-access checks. Anonymous readers or publish RoleReader tokens can supply a heading block ID to read full rendered content of publish-disabled documents that should be restricted.
A vulnerability allowing information disclosure exists in SiYuan versions prior to 3.7.3. This issue arises in the getHeadingDeleteTransaction, getHeadingLevelTransaction, and getHeadingInsertTransaction endpoints, which return rendered block DOM without proper publish-access checks. As a result, anonymous readers or those with a publish RoleReader token can supply a heading block ID to access the full rendered content of publish-disabled documents that should be restricted.
Users are advised to update to SiYuan version 3.7.3 or later, where this vulnerability has been patched.
