GitHub malicious-dependency incident touching protocol deps
Polymarket's assessment for RD-F-160 — scored not_assessed on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
v1-deferred. Malicious npm packages ts-bign@1.2.8 and big-nunber@5.0.2 (Feb 2026 StepSecurity report) target trading bot developer environments, not Polymarket's Foundry-based Solidity contract dependencies. Polymarket's core contracts are Solidity/Foundry — not npm. The malicious packages impersonate big.js and bignumber.js. No confirmed GitHub Advisory against packages actually consumed by Polymarket contracts.
