CVE-2026-72807
HighCVSS 8.0Exploitation Probability (EPSS)
Low risk10th percentile - higher than 10% of all known CVEs
Summary
SiYuan versions before v3.7.4 contain a second-order SQL injection vulnerability in attribute-view template columns that expose the queryBlocks function, which executes raw SQL using string substitution instead of parameterized queries. Attackers can distribute malicious SiYuan documents or packages with crafted template columns that execute arbitrary SQL on a victim's kernel when the package is imported and rendered, enabling read and write access across notebooks.
Risk Assessment
The risk includes unauthorized access to data and modification of notebooks, which could lead to leakage of sensitive information or data corruption.
Recommendation
It is recommended to update SiYuan to version v3.7.4 or later and use parameterized SQL queries in the queryBlocks function.
