CVE-2021-23380
MEDIUMCVE-2021-23380 is a medium-severity (CVSS 5.6) OS Command Injection vulnerability in roar-pidusage. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether CVE-2021-23380 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Arbitrary command execution in roar-pidusage
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
roar-pidusagenpmDescription
This affects all current versions of package roar-pidusage. If attacker-controlled user input is given to the stat function of this package on certain operating systems, it is possible for an attacker to execute arbitrary commands. This is due to use of the child_process exec function without input sanitization.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for roar-pidusage. 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 roar-pidusage has shipped for CVE-2021-23380 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-2021-23380 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-2021-23380. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
