CVE-2022-22779 — The Keybase Clients for macOS and Windows before version 5.9.0 fails to properly remove exploded messages initiated by a user

Medium CVSS 4.3

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.

Matched remediation archetype

Information disclosure and sensitive data exposure

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace sensitive data through responses, errors, logs, metrics, traces, caches, exports, files, backups, and client bundles.
  • Identify affected subjects, tenants, retention windows, access controls, and downstream copies without opening unnecessary sensitive records.
  • Review metadata, timing, status, length, and existence signals as well as direct content disclosure.

Remediate safely

  • Minimize collection and output, apply field-level authorization and redaction at a centralized boundary, and return generic external errors.
  • Remove secrets and sensitive data from logs, artifacts, URLs, caches, and client-side bundles; rotate credentials that may have been exposed.
  • Update the affected component and add synthetic-data tests for response, error, observability, and export paths.
