Apache HttpComponents AsyncClient 4.1 End of Life Date
Apache HttpComponents AsyncClient 4.1 end-of-life date, support status, and CVE risk. Dates read at the vendor's own lifecycle pages (hc.apache.org); the source of each date is on the product page.

Extended support for Apache HttpComponents exists: vetted vendors ship security patches past the official date. Right now that coverage spans Apache HttpComponents 5.1. Whether it covers Apache HttpComponents AsyncClient 4.1 is part of what we check. Leave an email and we reply within one business day with matched options and pricing guidance, or an honest "no vendor covers this version." Free, no obligation; vendors do not pay for placement.

What does Apache HttpComponents AsyncClient 4.1 end of life mean?
When Apache HttpComponents AsyncClient 4.1 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 Apache HttpComponents AsyncClient 4.1 past its EOL date creates a growing attack surface that a clean scan result does not rule out.
Migrate to Apache HttpComponents Client 5.6 or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
