GHSA-wpg7-2c88-r8xv is a high-severity (CVSS 7.5) CWE-212 vulnerability in simple-get. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-wpg7-2c88-r8xv is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Exposure of Sensitive Information in simple-get
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, a proxy for how much of the ecosystem is exposed.
simple-getnpmDescription
In versions of simple-get prior to 4.0.1, 3.1.1, and 2.8.2, when fetching a remote url with a cookie location response, headers will be followed, potentially resulting in an exposure of the session cookie to a third party.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 📦npm | simple-get | ≥ 4.0.0&&< 4.0.1 | 4.0.1 |
| 📦npm | simple-get | ≥ 3.0.0&&< 3.1.1 | 3.1.1 |
| 📦npm | simple-get | all versions | 2.8.2 |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for simple-get. 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 simple-get to 4.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-wpg7-2c88-r8xv 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-wpg7-2c88-r8xv 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-wpg7-2c88-r8xv. 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-wpg7-2c88-r8xv in your dependencies?
O3 detects GHSA-wpg7-2c88-r8xv across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
