Technical Details for CVE-2025-48127

Vulnerability Analysis

The vulnerability stems from Broken Access Control in the Push notification for Mobile and Web app plugin. The plugin exposes functionality without validating whether the requester holds the required capability or role. This category of flaw, classified under CWE-862 Missing Authorization, commonly appears in WordPress plugins that register AJAX or REST endpoints without calling current_user_can() or wp_verify_nonce() on privileged actions.

Because authentication is not required and the attack is executed over the network, an adversary can send crafted HTTP requests directly to vulnerable endpoints. Successful exploitation yields low-impact confidentiality and integrity effects, meaning attackers can read or modify a limited scope of plugin data. Availability is not affected according to the published CVSS vector.

Root Cause

The root cause is the absence of authorization checks on plugin actions that alter or expose plugin state. The plugin trusts that requests reaching its handlers originate from privileged users. Without capability verification or nonce validation, any anonymous HTTP client can invoke these actions.

Attack Vector

Exploitation requires only network access to a WordPress site running an affected plugin version. An attacker sends HTTP requests to the vulnerable plugin endpoint, bypassing role checks. No user interaction, credentials, or elevated privileges are required. Refer to the Patchstack advisory for endpoint-level technical details.

No verified public proof-of-concept code is available for this issue. Technical details should be consulted directly from the vendor advisory.

Detection Methods for CVE-2025-48127

Indicators of Compromise

Unexpected changes to push notification configuration, subscriber lists, or notification content within the WordPress admin interface
Unauthenticated HTTP POST or GET requests targeting admin-ajax.php or REST routes registered by the push-notification-mobile-and-web-app plugin
Access log entries showing repeated requests to plugin endpoints from a single external IP without a valid session cookie

Detection Strategies

Inventory WordPress installations and identify sites running Push notification for Mobile and Web app version 2.0.3 or earlier
Monitor web server access logs for anonymous requests referencing plugin-specific action names or REST namespaces
Correlate WordPress audit logs against outbound push notification traffic to detect unauthorized notification dispatch

Monitoring Recommendations

Enable WordPress activity logging plugins to capture administrative actions and API calls
Forward web server and WordPress logs to a centralized SIEM for retention and query
Alert on plugin option changes or new subscriber records created outside of expected administrative sessions

How to Mitigate CVE-2025-48127

Immediate Actions Required

Update Push notification for Mobile and Web app to a version later than 2.0.3 once the vendor publishes a fix
If no patched version is available, deactivate and remove the plugin from all affected WordPress installations
Review WordPress user accounts, plugin settings, and recently sent push notifications for signs of unauthorized modification

Patch Information

At the time of publication, the Patchstack advisory tracks this issue for versions through 2.0.3. Administrators should consult the Patchstack entry and the plugin's WordPress.org page for the latest patched release. Apply updates through the WordPress plugin manager or WP-CLI.

Workarounds

Deploy a Web Application Firewall (WAF) rule to block unauthenticated requests to the plugin's AJAX and REST endpoints
Restrict access to wp-admin/admin-ajax.php at the network edge for requests lacking valid authentication cookies
Remove or disable the plugin until the vendor issues a fix, replacing it with an alternative push notification solution if required

bash

# Configuration example: disable the plugin via WP-CLI until a patched version is released
wp plugin deactivate push-notification-mobile-and-web-app
wp plugin delete push-notification-mobile-and-web-app
