CVE-2025-49846

Cleartext message disclosure via invalid canOpenURL calls

Published Jul 3, 2025 · Updated Jul 3, 2025

Information disclosure in Wire iOS 3.111.1 through 3.124.0 allows physically proximate attackers to read cleartext messages from system logs. The client passes an invalid URL containing viewport-visible message text to canOpenURL(); when validation fails, iOS writes that text to its system log. Access requires physical control of an unlocked device, and the exposure is limited to messages displayed while an affected version was in use.
