CVE-2021-44458 — Linux users running Lens 5.2.6 and earlier could be compromised by visiting a malicious website
Critical
CVSS 9.6
Linux users running Lens 5.2.6 and earlier could be compromised by visiting a malicious website. The malicious website could make websocket connections from the victim's browser to Lens and so operate the local terminal feature. This would allow the attacker to execute arbitrary commands as the Lens user.

Matched remediation archetype
Authentication bypass and missing authentication
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
- Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
- Review session, token, credential, and proxy trust configuration without attempting account takeover.
Remediate safely
- Apply the supported fix and centralize fail-closed authentication before protected request handling.
- Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
- Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
