Assigner: VulnCheck

Description
@jitsi/electron-sdk before 10.0.5 exposes getDesktopSources() via contextBridge without requiring an active getDisplayMedia() picker, allowing any script in the meeting page to enumerate screens and windows. Attackers can call the jitsi-screen-sharing-get-sources IPC route to retrieve desktop thumbnails at arbitrary resolution without user consent or operating system permission prompts.

Executive Summary

This vulnerability in @jitsi/electron-sdk before version 10.0.5 allows any script in a meeting page to access screen-sharing sources without user consent. The getDesktopSources() function is exposed via contextBridge, enabling attackers to call the jitsi-screen-sharing-get-sources IPC route and retrieve desktop thumbnails at any resolution without OS-level permission prompts.

Detection Guidance

Check if your application uses @jitsi/electron-sdk versions before 10.0.5. Inspect Electron app logs for unauthorized calls to jitsi-screen-sharing-get-sources IPC route or getDesktopSources(). Monitor network traffic for unexpected screen thumbnail requests.

Impact Analysis

An attacker could exploit this to capture sensitive information displayed on your screen during a Jitsi meeting without your knowledge. This includes private documents, emails, or other confidential content visible on your desktop or applications.

Compliance Impact

This vulnerability could lead to unauthorized access to personal or sensitive data, violating GDPR's data protection principles and HIPAA's requirements for safeguarding protected health information. Organizations using affected versions may face compliance violations and legal consequences.

Mitigation Strategies

Upgrade to @jitsi/electron-sdk version 10.0.5 or later immediately. Disable screen sharing features if not required. Implement strict input validation for IPC routes in Electron apps. Review Electron security guidelines for context isolation and sandboxing.
