Vulnerability description
DayBreach CVE AI Research
CVE-2026-54068 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
The `/api/icon/getDynamicIcon` endpoint is explicitly excluded from authentication in SiYuan's kernel router (`router.go`, "不需要鉴权" -- no auth needed). When called with `type=8` and a valid block `id` parameter, this endpoint invokes `RenderDynamicIconContentTemplate`, which executes a Go template that includes the `querySQL` and `queryBlocks` functions. These functions run arbitrary SELECT statements against the SiYuan SQLite database. An unauthenticated network-adjacent attacker who knows a valid block ID can exfiltrate all user note content, tags, asset references, and block attributes from the database.
