CVE-2025-30887: WpEvently Authorization Bypass Vulnerability

CVE-2025-30887 Overview

CVE-2025-30887 is a missing authorization vulnerability in the magepeopleteam WpEvently (mage-eventpress) WordPress plugin. The flaw affects all versions up to and including 4.2.9. The plugin fails to enforce proper access control checks on one or more endpoints, allowing unauthenticated attackers to reach functionality that should be restricted to authorized users. The issue is classified under CWE-862: Missing Authorization and can be exploited remotely over the network without user interaction.

Critical Impact
Unauthenticated network-based attackers can bypass access control checks in WpEvently 4.2.9 and earlier, leading to limited unauthorized modification of plugin data.

Technical Details for CVE-2025-30887

Vulnerability Analysis

The WpEvently plugin exposes one or more actions that lack proper capability or nonce verification. Under WordPress security guidance, sensitive actions must be guarded by current_user_can() checks or equivalent role validation before execution. WpEvently omits or misconfigures these checks, resulting in broken access control on affected handlers.

Because the attack vector is network-based and requires no privileges or user interaction, an attacker can send crafted HTTP requests directly to the vulnerable endpoints. The scope of impact is limited primarily to integrity, meaning attackers can modify data exposed by the vulnerable actions without triggering a confidentiality or availability breach.

Root Cause

The root cause is the absence of a proper authorization check on plugin functionality. The plugin registers actions accessible via WordPress AJAX or REST routes without validating that the requester holds the required capability. This aligns directly with the [CWE-862] pattern where a software component performs a security-relevant operation but does not verify the user's authorization for that operation.

Attack Vector

An unauthenticated attacker sends crafted HTTP requests to the WordPress site hosting a vulnerable WpEvently instance. Because there is no privilege requirement, the attacker only needs the target URL to trigger the unauthorized action. The vulnerability manifests when the plugin's handler executes the requested operation without confirming the caller has appropriate permissions. See the Patchstack Vulnerability Report for additional technical details.

Detection Methods for CVE-2025-30887

Indicators of Compromise

Unexpected modifications to WpEvently plugin data, event records, or configuration entries in the WordPress database.
Access log entries showing unauthenticated POST requests to admin-ajax.php referencing WpEvently actions or to plugin-specific REST routes.
Requests originating from unusual IP addresses hitting mage-eventpress endpoints at high frequency.

Detection Strategies

Inventory WordPress installations and identify sites running WpEvently version 4.2.9 or earlier.
Review web server access logs for anomalous request patterns targeting WpEvently AJAX or REST endpoints without a valid authenticated session cookie.
Compare event and plugin option tables against known-good baselines to identify unauthorized modifications.

Monitoring Recommendations

Enable WordPress audit logging to capture plugin configuration changes and administrative actions.
Alert on repeated 200-response POSTs to WpEvently endpoints from clients that never authenticated to wp-login.php.
Monitor for new or modified events, categories, or bookings created outside expected administrative workflows.

How to Mitigate CVE-2025-30887

Immediate Actions Required

Identify all WordPress sites running WpEvently (mage-eventpress) and confirm plugin versions.
Update WpEvently to a version later than 4.2.9 once the vendor releases a patched build.
Restrict access to wp-admin/admin-ajax.php and plugin REST routes from untrusted networks where feasible.

Patch Information

At the time of publication, the vulnerability affects WpEvently through version 4.2.9. Administrators should consult the Patchstack Vulnerability Report and the vendor's plugin page for the latest fixed release. Apply the update through the WordPress plugin management interface or via WP-CLI.

Workarounds

Deactivate and remove the WpEvently plugin if a patched version is not yet available and the plugin is not business-critical.
Deploy a web application firewall (WAF) rule to block unauthenticated requests to WpEvently AJAX actions and REST endpoints.
Enforce IP allowlisting for administrative traffic and require authenticated sessions for all plugin actions where possible.

bash

# Example WP-CLI update once a patched release is available
wp plugin update mage-eventpress --version=<patched-version>

# Or deactivate the plugin as an interim workaround
wp plugin deactivate mage-eventpress
