CVE-2022-22779 (GCVE-0-2022-22779)

Vulnerability from cvelistv5 – Published: 2022-02-09 22:05 – Updated: 2024-09-17 00:05

Title

Retained exploded messages in Keybase clients for macOS and Windows

Summary

The Keybase Clients for macOS and Windows before version 5.9.0 fails to properly remove exploded messages initiated by a user. This can occur if the receiving user switches to a non-chat feature and places the host in a sleep state before the sending user explodes the messages. This could lead to disclosure of sensitive information which was meant to be deleted from a user’s filesystem.

Severity ?

3.7 (Low)
