CVE-2022-29160

Sensitive data retained after account deletion

Published May 20, 2022 · Updated Apr 22, 2025

Information disclosure in Nextcloud Android before 3.19.0 allows local users to recover sensitive data from deleted-account remnants. The account-removal cleanup process leaves sensitive tokens, images, and user-related details on the device after an account is deleted. A local user with access to the Android device and the affected app can misuse the residual information; the disclosed impact is confidentiality loss without reported integrity or availability effects.
