CVE-2025-30790: Chatbox Manager Authorization Bypass Flaw

CVE-2025-30790 Overview

CVE-2025-30790 is a Missing Authorization vulnerability [CWE-862] in the alexvtn Chatbox Manager (wa-chatbox-manager) WordPress plugin. The flaw affects all versions up to and including 1.2.2. Attackers can reach plugin functionality that is not properly constrained by access control lists (ACLs), enabling unauthenticated interaction with plugin actions that should require privileged access.

The issue impacts integrity of plugin data. It does not require user interaction or authentication and is exploitable over the network.

Critical Impact
Unauthenticated attackers can invoke plugin functionality that lacks capability or authorization checks, allowing tampering with Chatbox Manager settings or data on affected WordPress sites.

Affected Products

alexvtn Chatbox Manager (wa-chatbox-manager) WordPress plugin
Versions from n/a through <= 1.2.2
WordPress sites running the vulnerable plugin

Technical Details for CVE-2025-30790

Vulnerability Analysis

CVE-2025-30790 is a broken access control issue in the Chatbox Manager plugin for WordPress. The plugin exposes functionality that fails to verify whether the requesting user holds the required capability or role before executing sensitive actions. This maps to CWE-862 (Missing Authorization).

The vulnerability is exploitable over the network with low attack complexity and requires no privileges or user interaction. The impact is limited to integrity, meaning attackers can modify plugin state or trigger unauthorized actions but do not directly obtain confidential data or cause service disruption through this flaw.

Root Cause

The root cause is the absence of authorization checks on one or more plugin endpoints or AJAX handlers. WordPress plugins typically enforce access control by calling current_user_can() capability checks and validating nonces via check_ajax_referer() or wp_verify_nonce(). In wa-chatbox-manager versions up to 1.2.2, at least one handler omits these checks, allowing any visitor to invoke the underlying functionality.

Attack Vector

An unauthenticated remote attacker sends crafted HTTP requests directly to the vulnerable plugin endpoint. Because there is no capability check gating the handler, the plugin processes the request and executes the requested action. Refer to the Patchstack Vulnerability Advisory for detailed request-level information.

No verified public exploit code has been published for this issue.

Detection Methods for CVE-2025-30790

Indicators of Compromise

Unexpected changes to Chatbox Manager plugin settings or stored chatbox content on WordPress sites
Anonymous or unauthenticated HTTP POST requests to wa-chatbox-manager plugin endpoints or admin-ajax.php actions associated with the plugin
Web server access logs showing repeated requests to plugin PHP files from unauthenticated sessions

Detection Strategies

Inventory all WordPress installations and identify sites running wa-chatbox-manager version 1.2.2 or earlier
Review WordPress access logs for requests to plugin endpoints originating from clients without valid authentication cookies
Correlate plugin option changes in the wp_options table with the identity of the actor that triggered them

Monitoring Recommendations

Enable WordPress activity logging to record plugin configuration changes and administrative actions
Forward web server and WordPress application logs to a centralized log platform for retention and query
Alert on HTTP requests to plugin AJAX actions that do not carry a valid wp-admin session or nonce

How to Mitigate CVE-2025-30790

Immediate Actions Required

Identify all WordPress sites running the Chatbox Manager plugin at version 1.2.2 or earlier
Update the plugin to a patched release once the vendor publishes a fixed version, per the Patchstack advisory
If no fix is available, deactivate and remove the plugin until a patched version is released

Patch Information

At the time of publication, the advisory lists affected versions as n/a through <= 1.2.2. Administrators should consult the Patchstack Vulnerability Advisory and the plugin page on WordPress.org for the latest fixed version and upgrade guidance.

Workarounds

Deactivate the wa-chatbox-manager plugin until a patched release is installed
Restrict access to plugin endpoints and admin-ajax.php actions using a Web Application Firewall (WAF) rule that blocks unauthenticated requests to the vulnerable handlers
Limit administrative access to WordPress by IP allowlisting where operationally feasible

bash

# Configuration example: disable the vulnerable plugin via WP-CLI
wp plugin deactivate wa-chatbox-manager
wp plugin status wa-chatbox-manager
