+-   ([`7d0e4c6`](https://github.com/mCaptcha/mCaptcha/commit/7d0e4c6be4b0769921cda7681858ebe16ec9a07b)) Add `secret` parameter to token verification request payload(`/api/v1/pow/siteverify`) to mitigate a security issue that @gusted found:
+    > ...A malicious user could grab the sitekey
+    > and use that sitekey with mcaptcha to use it for their own server.
+    > While they can now go abuse it for illegal stuff or other stuff.
+    > You might decide, oh I don't want this! and terminate a legitimate
+    > siteKey.
+    > New request payload:
+    ```json
+    {
+    	"secret": "<your-users-secret>", // found in /settings in the dashbaord
+    	"token": "<token-presented-by-the-user>",
