Apache Log4j 1 End of Life Date
Apache Log4j 1 end-of-life date, support status, and CVE risk. Data reconciled from official vendor documentation and endoflife.date at every build; the source of each date is on the product page.
Apache Log4j 1 was released on January 8, 2001 and support ended on August 5, 2015 — a supported lifespan of 14 years and 7 months, longer than the 2 years and 6 months median for Apache Log4j releases. Its latest release on record is 1.2.17, published May 6, 2012 — 3 years and 3 months before support ended. It has been past its end-of-life date for 11 years and 3 months. 1 newer Apache Log4j release has shipped since.
Extended support for Apache Log4j exists: vetted vendors ship security patches past the official date. So far there are 10+ post-EOL CVE fixes documented in vendor release notes. Whether it covers Apache Log4j 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 Log4j 1 end of life mean?
When Apache Log4j 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 Log4j 1 past its EOL date creates a growing attack surface that a clean scan result does not rule out.
Migrate to Apache Log4j 2 or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
