CVE-2025-62877
CRITICALCVE-2025-62877 is a critical-severity (CVSS 9.8) CWE-1188 vulnerability in github.com/harvester/harvester-installer. O3 Security confirms whether CVE-2025-62877 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Harvest may expose OS default ssh login password via SUSE Virtualization Interactive Installer
Real-World Exposure
github.com/harvester/harvester-installer🐹github.com/harvester/harvester-installerReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
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
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐹Go | github.com/harvester/harvester-installer | ≥ 1.6.0 | No fix |
| 🐹Go | github.com/harvester/harvester-installer | ≥ 1.5.0 | No fix |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/harvester/harvester-installer. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of github.com/harvester/harvester-installer has shipped for CVE-2025-62877 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2025-62877 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2025-62877. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
