[CRITICAL] A live API bearer token is hardcoded in source and will be committed to git history; anyone with repo read access gets the key, and rotation requires a code change.

Fix: Read the key from configuration/env (like postJson's bearer) and fail closed when absent; rotate the leaked key immediately.

// Remove the constant; pass the bearer in from the caller via config,
    // the same way postJson(String, String, String) does.
    static String fetchWikiRaw(String baseUrl, String query, String bearer) {

[MEDIUM] The new fetchWikiRaw helper has no test, unlike the carefully tested bearer path in HttpFetcherTest; changed behavior (URL building, status handling, error path) is uncovered.

Fix: Add a unit test for URL construction/encoding and the non-200 path, using a stub Fetcher or by extracting the URL-building into a pure static method.

[HIGH] The user query is concatenated into the URL raw, so spaces or '&', '#', '=' break the request and let a malicious query inject extra query parameters (URL/query injection).

Fix: URL-encode the query with URLEncoder.encode(query, StandardCharsets.UTF_8), as Wiki.search and Search.web already do.

String url = baseUrl + "?action=query&list=search&format=json&srlimit=1&srsearch="
                + URLEncoder.encode(query, StandardCharsets.UTF_8);

[LOW] baseUrl is concatenated with no validation or normalization; a trailing slash or missing scheme produces a malformed URL, unlike Search which normalizes baseUrl with replaceAll("/+$", "").

Fix: Normalize baseUrl (strip trailing slashes) and guard against null/blank before building the URL.

String base = baseUrl == null ? "" : baseUrl.replaceAll("/+$", "");
        String url = base + "?action=query&list=search&format=json&srlimit=1&srsearch="
                + URLEncoder.encode(query, StandardCharsets.UTF_8);

[MEDIUM] A fresh HttpClient.newHttpClient() is built per call with no connect or request timeout, bypassing the class's configured http client and timeoutSeconds; a slow wiki can hang the calling thread indefinitely.

Fix: Reuse the shared this.http client and set .timeout(Duration.ofSeconds(timeoutSeconds)) on the request, as get()/postJson() do.

HttpRequest req = HttpRequest.newBuilder(URI.create(url))
                    .timeout(Duration.ofSeconds(timeoutSeconds))
                    .header("User-Agent", AGENT)
                    .header("Authorization", "Bearer " + bearer)
                    .GET()
                    .build();
            HttpResponse<String> resp = http.send(req, HttpResponse.BodyHandlers.ofString());

[HIGH] No User-Agent is sent; the class's own comment documents that pt.minecraft.wiki returns 403 to a default UA, so this helper will be rejected by the very wiki it targets.

Fix: Add the existing AGENT header (.header("User-Agent", AGENT)) to the request, matching get() and postJson().

HttpRequest req = HttpRequest.newBuilder(URI.create(url))
                    .header("User-Agent", AGENT)

[MEDIUM] e.printStackTrace() writes stack traces to stderr bypassing the plugin's warn sink, so failures are invisible to operators and inconsistent with the rest of HttpFetcher/Wiki which route errors through warn/IOException.

Fix: Throw or propagate via the caller's Consumer warn (as Wiki.lookup does) instead of swallowing with printStackTrace.

} catch (Exception e) {
            throw new IOException("Wiki search falhou: " + e.getMessage(), e);
