Description
Impact
What kind of vulnerability is it? Who is impacted?
Command Injection vulnerabilities in electerm:
A command injection vulnerability exists in github.com/elcterm/electerm/npm/install.js:130. The runLinux() function appends attacker-controlled remote version strings directly into an exec("rm -rf ...") command without validation.
Who is impacted: Users who run npm install -g electerm in Linux. An attacker who can control the remote release metadata (version string or release name) served by the project's update server could execute arbitrary system commands, tamper local files, and escalate compromise of development/runtime assets.
Patches
Has the problem been patched? What versions should users upgrade to?
Fixed in 59708b38c8a52f5db59d7d4eff98e31d573128ee, user no need to upgrade, the new version already published in npm
Workarounds
Is there a way for users to fix or remediate the vulnerability without upgrading?
no

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for electerm. 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 electerm to 3.3.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8x35-hph8-37hq 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 GHSA-8x35-hph8-37hq 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-8x35-hph8-37hq. 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-8x35-hph8-37hq in your dependencies?
O3 detects GHSA-8x35-hph8-37hq across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
