siyuan versions before v3.8.2 contain an authenticated SQL injection vulnerability in the fullTextSearchBlock endpoint's method=1 query parameter. Attackers can inject UNION SELECT statements to read the entire blocks table, bypassing publish-access controls and exposing all document content and sensitive attributes.
AnalysisAI
SQL injection in SiYuan's fullTextSearchBlock endpoint (versions before v3.8.2) allows read-level database access to the entire blocks table by injecting UNION SELECT statements into the method=1 query parameter. The vulnerability bypasses publish-access controls, exposing document content and sensitive block attributes that the operator intended to keep private. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The fullTextSearchBlock endpoint must be network-reachable on the SiYuan instance; SiYuan is often bound to localhost by default but may be exposed on LAN or internet in server/publish deployments. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N) rates this at 8.7, but the description explicitly labels it an 'authenticated SQL injection', directly contradicting the PR:N metric. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to SiYuan v3.8.2 or later, which resolves the injection per the vendor advisory GHSA-336w-67gx-gx2h. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all SiYuan deployments and confirm versions deployed across development, staging, and production; immediately restrict network access to the fullTextSearchBlock endpoint using firewall rules or reverse proxy if operationally feasible. …
