GHSA-99xx-83jm-h24m
HIGHGHSA-99xx-83jm-h24m is a high-severity (CVSS 7.8) OS Command Injection vulnerability in crmsh. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-99xx-83jm-h24m is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
ClusterLabs crmsh vulnerable to shell code injection
Blast Radius
crmshReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
An issue was discovered in ClusterLabs crmsh through 4.2.1. Local attackers able to call crm history (when crm is run) were able to execute commands via shell code injection to the crm history commandline, potentially allowing escalation of privileges.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for crmsh. 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 crmsh has shipped for GHSA-99xx-83jm-h24m 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 GHSA-99xx-83jm-h24m 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 GHSA-99xx-83jm-h24m. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-99xx-83jm-h24m in your dependencies?
O3 detects GHSA-99xx-83jm-h24m across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
