GHSA-9vh6-qfv6-vcqp is a high-severity (CVSS 8.8) CWE-74 vulnerability in snipe/snipe-it. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-9vh6-qfv6-vcqp is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
snipe-IT vulnerable to host header injection
Real-World Exposure
snipe/snipe-itReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
Snipe-IT is a free, open-source IT asset/license management systemIn Snipe-IT, versions v3.0-alpha to v5.3.7 are vulnerable to Host Header Injection. By sending a specially crafted host header in the reset password request, it is possible to send password reset links to users which once clicked lead to an attacker controlled server and thus leading to password reset token leak. This can lead to account take over.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | snipe/snipe-it | ≥ 3.0-alpha&&< 5.4.0 | 5.4.0 |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for snipe/snipe-it. 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 snipe/snipe-it to 5.4.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9vh6-qfv6-vcqp 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-9vh6-qfv6-vcqp 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-9vh6-qfv6-vcqp. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
