CVE-2024-9630: WPS Telegram Chat Auth Bypass Vulnerability

CVE-2024-9630 Overview

CVE-2024-9630 affects the WPS Telegram Chat plugin for WordPress in versions up to and including 4.6.0. The plugin fails to enforce a capability check when accessing messages exchanged through the Telegram Bot API. Unauthenticated attackers can retrieve message content by sending a network request to the vulnerable handler. The weakness is tracked as Missing Authorization [CWE-862] and results in disclosure of information the plugin transmits between the WordPress site and its associated Telegram bot.

Critical Impact
Unauthenticated remote attackers can read Telegram Bot API messages processed by the plugin without any user interaction or privileges.

Affected Products

10Web WPS Telegram Chat plugin for WordPress, all versions through 4.6.0
WordPress sites running the vulnerable plugin under the CPE cpe:2.3:a:10web:wps_telegram_chat
Any deployment exposing the plugin's public handler endpoint to the internet

Technical Details for CVE-2024-9630

Vulnerability Analysis

The WPS Telegram Chat plugin exposes a public handler that processes messages relayed to and from the Telegram Bot API. The handler executes without confirming that the caller holds a capability appropriate for reading those messages. Any unauthenticated visitor who reaches the endpoint can request the stored or in-transit message data.

The flaw is limited to confidentiality. Attackers cannot alter data or disrupt service through this vector, but they can harvest chat content that site owners expect to remain private between the WordPress installation and their Telegram bot. Sensitive customer conversations, order details, or support tickets routed through the plugin are exposed.

Root Cause

The root cause is a missing capability check in the plugin's public handler. WordPress plugins are expected to gate privileged actions using current_user_can() or a matching nonce verification. The vulnerable handler, referenced in the wps-telegram-chat-public-handler.php file at the public/partials path, omits these controls. Without authorization enforcement, the endpoint returns message data to any requester.

Attack Vector

Exploitation requires only network access to the WordPress site. An attacker issues an HTTP request to the plugin's public endpoint and receives the message content in the response. No authentication, session, or user interaction is required. The vulnerability is therefore reachable by automated scanners and mass exploitation tooling that enumerate WordPress plugins.

No verified proof-of-concept code has been published. Technical details on the vulnerable handler are available in the WordPress Plugin Handler Code and the Wordfence Vulnerability Report.

Detection Methods for CVE-2024-9630

Indicators of Compromise

Unauthenticated HTTP requests to the WPS Telegram Chat plugin's public handler endpoint, particularly from unfamiliar IP ranges or automated user agents
Web server access log entries referencing wps-telegram-chat paths without an associated authenticated WordPress session cookie
Unexpected outbound activity or reconnaissance immediately following requests to the plugin endpoint

Detection Strategies

Inventory WordPress sites using the 10web/wps_telegram_chat plugin and confirm the installed version against the 4.6.0 threshold
Review WordPress and reverse proxy logs for anonymous access patterns to plugin-controlled URLs
Correlate plugin endpoint requests with response sizes larger than expected for unauthenticated callers, which can indicate successful message retrieval

Monitoring Recommendations

Enable verbose logging on the WordPress front-end and forward events to a centralized log platform for retention and search
Alert on repeated unauthenticated requests to plugin AJAX or REST endpoints that return non-empty JSON payloads
Track plugin version drift across managed WordPress fleets to detect unpatched installations

How to Mitigate CVE-2024-9630

Immediate Actions Required

Update the WPS Telegram Chat plugin to a version later than 4.6.0 that includes the capability check fix
If a patched release is unavailable in your environment, deactivate and remove the plugin until an update can be applied
Rotate the Telegram Bot API token associated with the plugin to invalidate credentials that may have been observed in exposed messages

Patch Information

Remediation is available by upgrading to a fixed release of the WPS Telegram Chat plugin published after version 4.6.0. Refer to the Wordfence Vulnerability Report for the vendor's fixed version and to the WordPress Plugin Handler Code for the location of the vulnerable handler.

Workarounds

Restrict access to the plugin's public handler URL at the web server or WAF layer, allowing only trusted IP ranges
Deploy a WordPress security plugin or WAF rule that blocks unauthenticated requests to the WPS Telegram Chat endpoints
Audit Telegram bot conversations for sensitive data and remove or redact historical messages that no longer need to be retained

bash

# Example nginx rule to block unauthenticated access to the plugin handler
location ~* /wp-content/plugins/wps-telegram-chat/public/ {
    deny all;
    return 403;
}
