Apache Camel 4.18 LTS end of life
Apache Camel 4.18 LTS reaches end of life in February 2027, per Camel's download page. Camel supports only its two most recent LTS lines, each for about a year, so 4.18 will be replaced by the next LTS and stop receiving fixes roughly five months from now.

What actually breaks in the upgrade
The one-year LTS window is the real constraint
Camel states that LTS releases receive fixes for up to one year. Staying supported therefore means an LTS-to-LTS upgrade every year, indefinitely. Most enterprise integration estates do not upgrade on that cadence, which is how they end up unsupported without anyone deciding it.
Your options, costed honestly
Including the ones that do not involve buying anything from us.
| Option | What it is | Effort | Cost | Our view |
|---|---|---|---|---|
| Move to Camel 4.22 LTS | End of life August 2027. | Minor within 4.x | Low | Straightforward — and the clock restarts immediately. |
| OSSeva extended support | Patched 4.18.x past February 2027. | BOM swap | Per application estate | Decouples your upgrade cadence from Camel's. |
What OSSeva does for Apache Camel 4.18 LTS
OSSeva patches this line
OSSeva will patch Camel 4.18.x from its end-of-life date, as it does for expired 4.x LTS lines today.
Apache Camel extended supportWhat your auditor will say
Requires that system components are protected from known vulnerabilities by installing applicable security patches. A release line with no upstream patch stream cannot meet this by itself, whatever the scanner reports.
Vulnerability identification and remediation. Scanning satisfies identification. Remediation is what fails when the fix does not exist for the line you run.
