CVE-2024-9630 identifies an authorization bypass vulnerability classified under CWE-862 in the WPS Telegram Chat plugin for WordPress, affecting all versions up to and including 4.5.4. The root cause is a missing capability check when accessing messages sent via the Telegram Bot API, which allows unauthenticated attackers to retrieve these messages without proper authorization. This flaw arises because the plugin fails to verify user permissions before granting access to sensitive chat data, violating the principle of least privilege. The vulnerability can be exploited remotely without requiring user interaction or authentication, increasing its accessibility to attackers. The CVSS v3.1 base score is 5.4 (medium), with vector metrics indicating network attack vector (AV:N), low attack complexity (AC:L), low privileges required (PR:L), no user interaction (UI:N), unchanged scope (S:U), and limited confidentiality and integrity impact (C:L/I:L/A:N). Although no public exploits have been reported yet, the exposure of Telegram chat messages could lead to information disclosure, potentially compromising private or business communications. The vulnerability affects any WordPress site running the vulnerable plugin version, which is widely used for integrating Telegram chat functionality. No official patches or updates have been linked yet, so mitigation relies on configuration changes or plugin deactivation. The vulnerability highlights the importance of proper authorization checks in plugins handling sensitive data and the risks posed by third-party WordPress extensions.

The primary impact of CVE-2024-9630 is unauthorized disclosure of messages sent through the Telegram Bot API integrated via the WPS Telegram Chat plugin. This can lead to exposure of sensitive or confidential communications, potentially resulting in privacy violations, leakage of business intelligence, or reputational damage. Since the vulnerability does not affect availability or allow message modification, the integrity and availability impacts are limited. However, the ease of exploitation without authentication or user interaction increases the risk of widespread unauthorized access. Organizations relying on this plugin for customer or internal communications may face compliance issues if sensitive data is exposed. Attackers could use the disclosed information for social engineering, phishing, or further targeted attacks. The lack of known exploits in the wild suggests limited active exploitation currently, but the vulnerability remains a significant risk until patched. The global reach of WordPress and Telegram means that organizations worldwide, especially those using this plugin for Telegram integration, are potentially affected.

1. Immediately audit and restrict access to the WPS Telegram Chat plugin settings and message data to trusted administrators only. 2. Temporarily disable or deactivate the WPS Telegram Chat plugin until an official patch or update addressing CVE-2024-9630 is released. 3. Monitor WordPress plugin repositories and vendor communications for security updates or patches and apply them promptly. 4. Review and harden WordPress user roles and capabilities to minimize privilege levels, ensuring only necessary users have access to plugin features. 5. Implement web application firewall (WAF) rules to detect and block unauthorized attempts to access Telegram chat message endpoints. 6. Conduct regular security assessments of third-party plugins, focusing on authorization and authentication controls. 7. Educate site administrators about the risks of installing plugins without proper security vetting and encourage use of plugins with active maintenance and security support. 8. Consider alternative secure Telegram integration methods that enforce strict authorization checks. 9. Enable logging and alerting on suspicious access patterns to Telegram chat data endpoints to detect potential exploitation attempts early.
