CVE-2022-24886

Contact disclosure via implicit notification PendingIntent

Published Apr 27, 2022 · Updated Apr 23, 2025

Exposure of Sensitive Information in Nextcloud Android app before 3.19.0 allows local users to read contacts via notification permission. An implicit notification PendingIntent lets any application holding notification permission invoke Nextcloud contact access when Nextcloud itself has Contacts permission without requesting it for that operation. The attacker must share the Android device and obtain notification permission; the demonstrated consequence is unauthorized contact confidentiality loss without integrity or availability impact.
