The vulnerability identified as CVE-2025-11760 affects the eRoom – Webinar & Meeting Plugin for Zoom, Google Meet, Microsoft Teams, a WordPress plugin designed to integrate popular video conferencing platforms into websites. The core issue is the exposure of Zoom SDK secret keys within client-side JavaScript embedded in the meeting view template. These secret keys, specifically the sdk_secret, are intended to remain confidential on the server side to prevent unauthorized use. However, due to improper handling, the plugin includes these secrets in the client-side code, making them accessible to any visitor of the webpage without requiring authentication or interaction. An attacker can extract the sdk_secret and use it to generate valid JSON Web Tokens (JWTs), which are used to authenticate and authorize access to Zoom meetings. This unauthorized access could allow attackers to join meetings, potentially eavesdrop, or gather sensitive information shared during sessions. The vulnerability is classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) and has a CVSS 3.1 base score of 5.3, indicating medium severity. The attack vector is network-based with low attack complexity, no privileges required, and no user interaction needed. The scope is unchanged, and the impact affects confidentiality only, with no direct impact on integrity or availability. No patches or fixes are currently linked, and no known exploits have been reported in the wild as of the publication date. Organizations using this plugin should be aware of the risk posed by the exposure of secret keys and the potential for unauthorized meeting access.

For European organizations, this vulnerability poses a significant risk to the confidentiality of virtual meetings conducted via Zoom integrated through the vulnerable plugin. Unauthorized access to meetings could lead to exposure of sensitive corporate information, intellectual property, or personal data, potentially violating GDPR requirements. The impact is particularly critical for sectors relying heavily on secure communications, such as finance, healthcare, legal, and government institutions. Although the vulnerability does not affect data integrity or availability, the breach of confidentiality alone can result in reputational damage, regulatory penalties, and loss of trust. Since exploitation requires no authentication or user interaction, the risk of automated or opportunistic attacks is elevated. Organizations using WordPress sites with this plugin for webinar or meeting functionalities are at risk of unauthorized meeting infiltration, which could facilitate espionage, data leakage, or social engineering attacks. The absence of known exploits in the wild provides a window for proactive mitigation but should not lead to complacency.

Immediate mitigation should focus on removing any Zoom SDK secret keys from client-side JavaScript to prevent exposure. Administrators should audit the plugin’s code and configuration to ensure secrets are stored and used exclusively on the server side. Until an official patch is released, consider disabling the plugin or replacing it with alternative secure solutions for webinar and meeting integrations. Implement strict access controls and monitoring on WordPress administrative interfaces to prevent unauthorized changes. Employ network-level protections such as Web Application Firewalls (WAFs) to detect and block suspicious requests targeting the plugin’s meeting views. Regularly review logs for unusual access patterns that may indicate exploitation attempts. Educate users and administrators about the risks of exposing sensitive keys and the importance of secure coding practices. Once a vendor patch is available, prioritize timely updates. Additionally, consider rotating Zoom SDK secrets and credentials to invalidate any potentially compromised tokens. Finally, conduct security assessments of all third-party plugins integrated into WordPress environments to identify similar risks.
