## 🧾 Detailed a Description

### CVE-2025-8091 — Authenticated (Contributor+) Information Disclosure

 - **Affected Component**: get_single_event_data()
 - **Attack Vector**: Specify any event ID, including private or draft posts
 - **Trigger**: An authenticated user passes the target event ID to the API/endpoint
 - **Impact**: Disclosure of sensitive details from unpublished events created by an administrator, including title, full description, custom fields, location, and organizer information
 - **PoC**:
  1. Login as a Contributor in some way.
  2. Guess the sequential event ID and view private information using the following short code.`[add_single_eventon id="xxxx"]`
  3. Running the preview causes information leakage.

## ❓Reason for the vulnerability
 The post_type parameter is not properly validated, allowing retrieval of unintended post types including private or draft events.
 ### Proposed Fix:
 - Explicitly whitelist the allowed `post_type` before executing the query.
 - Apply proper capability checks such as `current_user_can('read_private_ajde_events')` for private content.
 - Limit `post_status` to publish for users without the necessary privileges.
