CVE-2025-68589 identifies a missing authorization vulnerability in the WP Socio WP Telegram Widget and Join Link WordPress plugin, specifically affecting versions up to 2.2.11. The vulnerability arises from incorrectly configured access control security levels, which means that the plugin fails to properly verify whether a user has the necessary permissions before allowing certain actions. This missing authorization can allow an attacker, potentially even an unauthenticated user depending on the plugin's configuration, to perform unauthorized operations such as modifying widget settings, injecting malicious content, or accessing sensitive data related to the Telegram widget integration. The plugin is designed to embed Telegram join links and widgets into WordPress sites, facilitating user engagement via Telegram channels. The lack of proper authorization checks undermines the integrity of this integration and could be exploited to manipulate the widget or disrupt its intended functionality. Although no exploits have been reported in the wild yet, the vulnerability is publicly disclosed and thus presents a risk of exploitation. The absence of a CVSS score requires an assessment based on the vulnerability's characteristics: it impacts integrity and potentially confidentiality, is relatively easy to exploit due to missing authorization, and affects a widely used WordPress plugin. The vulnerability does not require user interaction but may require some level of access depending on the site’s configuration. The plugin’s market penetration in Europe, combined with the widespread use of WordPress, makes this a relevant threat for European organizations relying on this plugin for Telegram integration.

For European organizations, this vulnerability could lead to unauthorized changes to website content or widget behavior, potentially damaging the organization's reputation and user trust. Attackers might inject malicious links or content via the Telegram widget, which could be used for phishing or spreading malware. The integrity of the website's communication channels with users via Telegram could be compromised, affecting customer engagement and operational continuity. Additionally, if sensitive information related to Telegram group membership or communication is exposed, it could lead to confidentiality breaches. Organizations in sectors with high reliance on digital communication and customer interaction, such as e-commerce, media, and public services, are particularly at risk. The impact is heightened in regulated environments where data protection and website integrity are critical. The absence of known exploits currently limits immediate risk but does not diminish the potential for future attacks once exploit code becomes available.

Organizations should immediately audit their WordPress installations to identify the presence of the WP Socio WP Telegram Widget and Join Link plugin and verify the version in use. Until an official patch is released, restrict access to WordPress administrative interfaces to trusted personnel only, employing strong authentication mechanisms such as multi-factor authentication. Implement strict role-based access controls to limit who can modify plugin settings. Monitor web server and application logs for unusual activity related to the Telegram widget endpoints. Consider temporarily disabling the plugin if it is not critical to operations or if adequate access controls cannot be ensured. Stay informed about vendor updates and apply patches promptly once available. Additionally, conduct regular security assessments and vulnerability scans focusing on WordPress plugins to detect similar authorization issues proactively. Employ web application firewalls (WAFs) with custom rules to block suspicious requests targeting the plugin’s functionality. Finally, educate site administrators about the risks of unauthorized plugin modifications and the importance of timely updates.
