CVE-2022-22779: Keybase

Low severity, CVSS 3.7. EPSS: 0.8% chance of exploitation in the next 30 days.

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.

Affected products

• Keybase Keybase: before 5.9.0 (fixed in 5.9.0)
