Jenkins 2.426 End of Life Date
Jenkins 2.426 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.
Jenkins 2.426 was released on October 3, 2023 and support ended on February 21, 2024 — a supported lifespan of 5 months, in line with the 4 months median for Jenkins LTS releases. It was a long-term support (LTS) release, so it received a longer patch window than the interim releases around it. The last patch it will ever receive is 2.426.3, published January 22, 2024 — 30 days before support ended. It has been without security patches for 2 years and 8 months. 11 newer Jenkins releases have shipped since.

What does Jenkins 2.426 end of life mean?
When Jenkins 2.426 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 Jenkins 2.426 past its EOL date creates a growing attack surface that a clean scan result does not rule out.
Migrate to Jenkins 2.580 or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
