Not automatically, but it is a risk an auditor can reasonably ask about. An end-of-life runtime no longer gets security fixes from its maintainers, so your vulnerability management control has a gap you cannot patch around. Track support dates, plan upgrades, and record exceptions when you must stay behind.
Why runtimes matter as dependencies
The language runtime is the largest dependency in your stack. Every service runs on it. When a version reaches end of life, new vulnerabilities found afterward are typically fixed only in supported lines. Your scanner may show nothing, because no advisory is written for the old version, which is exactly why teams get surprised. A silent report is not a clean bill of health.
Read the support policy, not a blog
Support windows are published by the projects. The Node.js release page explains that major versions enter a Current status for six months, and that historically even numbered releases move to Active LTS while odd numbered ones become unsupported after six months. It also states that starting with Node.js 27 the cycle will be annual and every major version will move to LTS after its Current phase. Because these rules change, check the project's page directly when you plan, and do not rely on a rule of thumb.
Other runtimes publish their own schedules. Write the source link next to each version in your inventory.
A tracking table you can keep
| Component | Version in use | Support ends | Owner | Upgrade target |
|---|---|---|---|---|
| Language runtime, service A | Fill in | Check project page | Named person | Quarter |
| Base image OS | Fill in | Check vendor page | Named person | Quarter |
| Framework | Fill in | Check project page | Named person | Quarter |
Review it monthly. Anything ending within two quarters gets an upgrade ticket now.
What to put in policy
State that production systems run supported versions of runtimes and operating system images, and that exceptions are recorded with a compensating control and an end date. That is a reasonable control for a small team, and it gives you a place to document the legacy service that cannot move yet.
Compensating controls when you must stay
If a legacy service is stuck on an unsupported runtime:
- Isolate it from the internet where possible.
- Restrict what it can reach on the network.
- Reduce its privileges and secrets.
- Add monitoring for unusual behavior.
- Put a retirement or upgrade date on the exception.
Those steps do not make the runtime safe, and you should not describe them that way. They reduce exposure while you plan the move.
What an auditor may ask
They may sample a service and ask what runtime version it uses and whether it is supported. If you can answer from your tracking table in a minute, that is a good sign. If you need to ask the team, build the table first.
Where Safeguard fits
Safeguard's asset discovery and dependency scanning help you find what runs where and which components you ship, so the support table starts from real data. Free scan: https://gold.safeguard.sh/scan.
Quick check
My scanner shows no issues on an end-of-life version. Am I fine?
Not necessarily. Unsupported versions often stop receiving advisories, so silence can mean no one is looking.
Can I stay on an old runtime during the audit?
Yes with a recorded exception, compensating controls and a dated plan. Say so honestly if asked.
