Case & protocol details
Audit assessment
Review priorities based on the documented failure pattern in GMX V1 Perps (September 2022).
Critical checks
- Verify every sensitive logic path is guarded by appropriate access controls and input validation - see the Oracle Manipulation & Price Manipulation attack class for patterns
- Audit oracle price feeds for manipulation risks - ensure time-weighted average prices (TWAPs) or multi-source aggregators are used, not spot prices
