# CVE-2025-62877: Harvest May Expose OS Default SSH Login Password Via SUSE Virtualization Interactive Installer

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.5% , percentile 43: FIRST’s model estimates a 0.5% chance of exploitation activity in the next 30 days, higher than 43% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes github.com/harvester/harvester-installer (Go) >= 1.6.0, <= 1.6.1, no fixed version listed ; github.com/harvester/harvester-installer (Go) >= 1.5.0, <= 1.5.2, no fixed version listed . Check your lockfile, including transitive dependencies.

## What it is

Projects using the SUSE Virtualization (Harvester) environment may expose the OS default ssh login password if they are using the 1.5.x or 1.6.x interactive installer to either create a new cluster or add new hosts to an existing cluster. The environment is not affected if the PXE boot mechanism is utilized along with the Harvester configuration setup.

## Affected packages

- Go `github.com/harvester/harvester-installer` >= 1.6.0, <= 1.6.1 → fixed: none listed
- Go `github.com/harvester/harvester-installer` >= 1.5.0, <= 1.5.2 → fixed: none listed

## Affected products (CVE record)

- SUSE harvester: 1.6.0, 1.5.0

## Severity

- suse CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.51% probability of exploitation activity in the next 30 days; percentile 43.
