Security readout for executives and security teams
Cryptocat versions before 2.0.22 had a remote script injection flaw caused by insufficient input sanitization. In plain terms, untrusted content could be interpreted as script inside the chat application. The available sources do not provide CVSS scoring or evidence of active exploitation. Exposure is most likely limited to legacy Cryptocat installations or archived browser/client deployments running versions before 2.0.22. Organizations that never used Cryptocat, or that removed it, are unlikely to be exposed. Low operational priority unless legacy Cryptocat use is confirmed. If present, remediate promptly because chat tools handle sensitive communications and script injection can undermine user trust and confidentiality. Mitigation focus: Inventory endpoints and archives for Cryptocat installations.; Remove unsupported Cryptocat clients where business use is unnecessary.; Upgrade any required Cryptocat instance to 2.0.22 or later..
