What does Cortex XDR 4.2 end of life mean?
When Cortex XDR 4.2 reaches end of life, the maintainers stop issuing security patches for this version. CVEs discovered after the EOL date are publicly disclosed on the National Vulnerability Database with no patch available. Exploit code frequently appears on GitHub within days of disclosure.
The CVE blind spot: A CVE-based scan does not show the ongoing accumulation of unpatched vulnerabilities in EOL software versions. Some scanners flag unsupported versions of common products, but coverage varies, and none of them give you the date in advance. Running Cortex XDR 4.2 past its EOL date creates a growing attack surface that a clean scan result does not rule out.
Migrate to Cortex XDR 9.3 or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.

Is Cortex XDR 4.2 still supported?
No. Cortex XDR 4.2 reached end of life on March 1, 2022 and is no longer receiving security patches.
What should I upgrade to from Cortex XDR 4.2?
The recommended upgrade from Cortex XDR 4.2 is
Cortex XDR 9.3 — the latest actively supported version. Check the
Cortex XDR full timeline for all supported versions.
What are the security risks of running Cortex XDR 4.2 past EOL?
When Cortex XDR 4.2 reaches end of life, the maintainers stop issuing security patches. Any CVEs disclosed after the EOL date accumulate with no vendor fix. A CVE-based scan does not show this — it is the CVE blind spot; some scanners flag unsupported versions of common products, but coverage varies and none give the date in advance. Organizations running EOL Cortex XDR should migrate immediately or implement compensating controls.
