MuleSoft Runtime 4.9 LTS 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.
MuleSoft Runtime 4.9-lts was released on February 28, 2025 and support is scheduled to end on February 29, 2028 — a planned supported lifespan of 3 years, shorter than the 5 years and 6 months median for MuleSoft Runtime LTS releases.

What does MuleSoft Runtime 4.9 LTS end of life mean?
When MuleSoft Runtime 4.9 LTS 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: Most vulnerability scanners check for known CVEs but do not flag the ongoing accumulation of unpatched vulnerabilities in EOL software versions. Running MuleSoft Runtime 4.9 LTS past its EOL date creates a permanently growing attack surface that standard security tooling will not surface.
Migrate to MuleSoft Runtime 4.9 LTS or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
