CVE-2026-92299
@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.
