    "summary": "### Summary The `/api/filetree/searchDocs` endpoint concatenates the caller-supplied search keyword directly into a SQL statement with no escaping and no parameter binding. The endpoint is gated by `CheckAuth` only reachable by the publish RoleReader token, and by the anonymous account when `Publish.Auth.Enable` is `false`. The resulting statement runs on a read-write SQLite handle through a driver that executes stacked (`;`-separated) statements, against the global `blocks` table spanning all cleartext notebooks. An unauthenticated request can therefore read and write database content across every non-encrypted notebook on the instance. ### Details Data flow, unescaped and unbound at every hop: - `searchDocs` (`kernel/api/filetree.go`): `k := arg[\"k\"].(string)` passed straight to `model.SearchDocs(k, …)`, no sanitization. - `SearchDocs` (`kernel/model/file.go`): after `TrimSpace` and `strings.Fields`, each token is spliced into a single-quoted `LIKE` literal by concatenation `condition.WriteString(\"(hpath LIKE '%\" + k + \"%'\")`. No escaping, no `''` doubling, no bind placeholder. - `NAMFilter` (`kernel/conf/search.go`): appends `\" OR name LIKE '%\" + keyword + \"%'\"` (and `alias`, `memo`) the same way, enabled by default. - `QueryRootBlockByCondition` (`kernel/sql/block_query.go`): `\"SELECT *, … FROM blocks WHERE type = 'd' AND \" + condition + \" ORDER BY … LIMIT …\"` passed to `query(sqlStmt)`. The only value-inspecting guard is `ast.IsNodeIDPattern(keyword)`, which merely route",
