Description

The SAP HANA Node.js client package versions from 2.0.0 before 2.21.31 is impacted by Prototype Pollution vulnerability allowing an attacker to add arbitrary properties to global object prototypes. This is due to improper user input sanitation when using the nestTables feature causing low impact on the availability of the application. This has no impact on Confidentiality and Integrity.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update @sap/hana-client to 2.21.31 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-45277 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.
