Auto-added after CISA flagged Samba as actively exploited (KEV catalog). Version and lifecycle mapping is pending review, so this is assessed at the product level and is never reported as a confident "healthy".
Summary iPlain-English security verdict for Samba, generated from its current health score, actively-exploited vulnerabilities, and latest supported version.
Samba currently scores 97/100 — healthy. 2 actively-exploited vulnerabilities (CISA KEV) affect older releases (e.g. CVE-2017-7494) — staying on the latest supported version keeps you clear of them. The latest supported release is 4.25.1. It's on the latest patch with no significant known issues — keep it current.
Disclosure trend iNew CVEs published for Samba each year (NVD). A higher bar means more disclosures that year — more scrutiny, not necessarily less safe.
2 of its known vulnerabilities are linked to ransomware campaigns (CISA KEV).
Patch priority — what to act on iThe issues to fix first — actively exploited (CISA KEV) first, then by exploitation probability (EPSS), then severity. Each row's "→ fixed in" is the earliest version that patches it; "see advisory" means no fixed version is published.
Most urgent first — actively exploited, then likeliest to be exploited.

Is Samba safe and patched?
Samba currently scores 97/100 — healthy. 2 actively-exploited vulnerabilities (CISA KEV) affect older releases (e.g. CVE-2017-7494) — staying on the latest supported version keeps you clear of them. The latest supported release is 4.25.1. It's on the latest patch with no significant known issues — keep it current.
What should I do about Samba now?
Upgrade Samba to the latest supported release (4.25.1) or later, which clears the actively-exploited issues affecting older versions, then confirm against Samba's official advisory.
Why is Samba listed on IsItPatched?
Samba was added automatically because CISA's Known Exploited Vulnerabilities (KEV) catalog flagged it as actively exploited in the wild. IsItPatched tracks its known CVEs, severity (CVSS), exploitation probability (EPSS) and KEV status from public data; its version and lifecycle mapping is verified over time.
Has Samba been actively exploited?
Yes. CISA added Samba to its Known Exploited Vulnerabilities (KEV) catalog after confirming exploitation in the wild — the triggering vulnerability is CVE-2017-7494. Make sure you are running a patched, supported version of Samba and confirm it against Samba's security advisory.
When does Samba reach end-of-life?
The latest supported Samba release is 4.25.1. After end-of-life a release no longer receives security patches.
Which versions of Samba are still receiving security updates?
Supported Samba release lines (latest 4.25.1): 4.25, 4.24, 4.23. End-of-life releases no longer receive security patches.
Informational only, from public data (NVD · CISA KEV · EPSS · endoflife.date), and can lag or miss vendor-specific fixes. Always confirm against Samba's official advisory before you patch or upgrade.
