Removed the spurious `status` param; all format/kind filtering is now applied client-side via `filteredEntries`, which already had the correct logic. - **Toggle/refresh URI corruption** — `toggle_ontology` and `refresh_ontology` applied `.removesuffix("/toggle")` / `.removesuffix("/refresh")` to the captured path parameter, which would silently corrupt any ontology URI that legitimately ends with those strings. Starlette's route regex (`/{uri:path}/toggle`) already strips the literal suffix via backtracking, so the `removesuffix` calls were removed and the raw `ontology_uri` parameter is used directly. - - **SSRF in URL fetch** — `_fetch_url_sync()` accepted arbitrary user-supplied URLs and called `requests.get()` with no validation, enabling server-side request forgery against internal services. Added `_validate_fetch_url()` which rejects non-`http`/`https` schemes and resolves the hostname via `socket.getaddrinfo`, blocking loopback, private, link-local, reserved, and multicast addresses. Applied to all three fetch sites: preview, load, and refresh. + - **SSRF in URL fetch** — `_fetch_url_sync()` accepted arbitrary user-supplied URLs and called `requests.get()` with no validation, enabling server-side request forgery against internal services. Added `_validate_fetch_url()` which rejects non-`http`/`https` schemes and resolves the hostname via `socket.getaddrinfo`, blocking loopback, private, link-local, reserved, and multicast addresses. - **File upload format misdetected** — the file picker accepted `.xml` and `.json` but `fmtMap` had no entries for those extensions, causing them to default to `turtle`. Added `xml: "xml"` and `json: "json-ld"` mappings. Changed the unknown-extension fallback from `|| "turtle"` to `?? ""` (empty string), and omit the `format` key from the request body when empty so the backend `_detect_format()` runs instead of receiving a forced incorrect value. Also added `.n3` to the accepted extension list and dropzone hint. - **Inconsistent XML hardening** — `_parse_rdf_sync()` called `rdflib.Graph().parse()` directly, bypassing the `defusedxml`-based XXE protection already present in `semantica/explorer/utils/rdf_parser.py`. Now routes through `_safe_parse_rdf()` from that module, applying consistent protection for all RDF/XML parse paths. - **Search scans whole graph** (`GET /api/ontology/search`) — the endpoint fetched up to 999 999 nodes and performed a linear Python substring scan on every request. Replaced with `session.search(q, limit * 6)` which uses the `GraphSearchIndex`; results are then post-filtered by `_SEARCHABLE_TYPES` and `entity_type` before being returned up to the requested limit.
