CVE-2020-7618
MEDIUMCVE-2020-7618 is a medium-severity (CVSS 5.3) CWE-1321 vulnerability in sds. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether CVE-2020-7618 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Prototype Pollution in sds
Real-World Exposure
sdsReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects npm packages — download data is not available via public APIs for these ecosystems.
Description
Affected versions of sds are vulnerable to prototype pollution. The set function does not restrict the modification of an Object's prototype, which may allow an attacker to add or modify an existing property that will exist on all objects.
Recommendation
Upgrade to version 4.0.0 or later
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 📦npm | sds | all versions | 4.0.0 |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for sds. 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 sds to 4.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2020-7618 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 CVE-2020-7618 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-2020-7618. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2020-7618 in your dependencies?
O3 detects CVE-2020-7618 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
