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

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for sds, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. 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.

  3. 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.
