CVE-2026-119407 · Severity: high · CVSS 7.1 · Published 2026-10-30

Technical details

The loadSession function improperly accepts guest_user_id and guest_access_token parameters from URL fragment identifiers, allowing unauthenticated remote attackers to inject credentials without proper validation. An attacker can craft a malicious URL and social engineer a logged-in user to click it, triggering a forced guest session that overwrites the current session and irreversibly destroys end-to-end encryption keys stored locally. No user interaction beyond clicking a link is required beyond the initial social engineering.
