Summary

SiYuan before v3.8.7 contains an SQL injection flaw (CWE-89) because the op and type=3 query values in history search are not escaped. An attacker holding an admin token can send crafted requests to the searchHistory or getHistoryItems endpoints to read history.db, including deleted document content, titles and paths. CISA's SSVC data rates exploitation as proof of concept.
