GHSA-5v25-xr56-phph
HIGHGHSA-5v25-xr56-phph is a high-severity (CVSS 8.1) OS Command Injection vulnerability in clamscan. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-5v25-xr56-phph is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

clamscannpmDescription
clamscan through 1.2.0 is vulnerable to Command Injection. It is possible to inject arbitrary commands as part of the _is_clamav_binary function located within Index.js. It should be noted that this vulnerability requires a pre-requisite that a folder should be created with the same command that will be chained to execute. This lowers the risk of this issue.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 📦npm | clamscan | all versions | 1.3.0 |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for clamscan. 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 clamscan to 1.3.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5v25-xr56-phph 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-5v25-xr56-phph 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-5v25-xr56-phph. 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-5v25-xr56-phph in your dependencies?
O3 detects GHSA-5v25-xr56-phph across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
