CVE-2026-0980
HIGHCVE-2026-0980 is a high-severity (CVSS 8.3) OS Command Injection vulnerability in rubyipmi. O3 Security confirms whether CVE-2026-0980 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Rubyipmi: red hat satellite: remote code execution in rubyipmi via malicious bmc username
Real-World Exposure
rubyipmiReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects RubyGems packages — download data is not available via public APIs for these ecosystems.
Description
A flaw was found in rubyipmi, a gem used in the Baseboard Management Controller (BMC) component of Red Hat Satellite. An authenticated attacker with host creation or update permissions could exploit this vulnerability by crafting a malicious username for the BMC interface. This could lead to remote code execution (RCE) on the system.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 💎RubyGems | rubyipmi | all versions | 0.13.0 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for rubyipmi. 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.
Fix
Update rubyipmi to 0.13.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-0980 is resolved across your whole dependency graph.
Workarounds
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-2026-0980 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-2026-0980. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2026-0980 in your dependencies?
O3 detects CVE-2026-0980 across RubyGems dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
