CVE-2026-48007
Overview
CVE-2026-48007 is a known-severity vulnerability. It was published on August 7, 2026.
Technical Description
Element Call is a native Matrix video conferencing application. Versions 0.5.17 through 0.19.3 report analytics data to a PostHog server, when configured to by a `posthog` key in config.json or by the `posthogApiHost` and `posthogApiKey` URL parameters. Several fields of this data (`$initial_person_info`, `$session_entry_url`, and `$current_url`) were found to contain the full URL of the user's visited page, including the fragment. Users of a standalone Element Call ‘SPA’ instance such as https://call.element.io may therefore have reported the full URLs of certain calls, including encryption passwords, to the configured PostHog server, potentially compromising the confidentiality of the calls to actors who could access both the PostHog analytics data and the encrypted media streams. The same issue is present in Element Call's embedded package, but in practice it does not impact applications using this package (including Element Web, Element Desktop, Element X iOS, and Element X Android
