CVE-2026-116170 · Severity: medium · CVSS 4.9 · Published 2026-10-25

SiYuan is an open-source note-taking application that maintains a searchable history database. An administrator with the API token can inject SQL commands via search parameters to exfiltrate deleted notes, including their content, titles, and file paths. This allows unauthorized disclosure of sensitive information that users intended to be permanently deleted.

## Technical details

The history search endpoints in kernel/model/history.go concatenate the `op` and `query` parameters directly into SQL WHERE clauses without escaping when `type=3` (DocID search), then execute the result against history.db via raw SQL sinks with no validation. An authenticated admin (API token holder) can send UNION SELECT payloads to /api/history/searchHistory or /api/history/getHistoryItems to bypass filters and extract arbitrary history records.
