[cite_start]During an independent security research phase, I identified a high-impact logic vulnerability within the GMXV2Leverage Trading PositionParser contract. This flaw could compromise protocol safety under specific execution conditions.

• [cite_start]Contract: PositionParser (GMX V2) [cite: 21, 29]
• [cite_start]Language: Solidity 0.8.19
• [cite_start]Validation Tool: Foundry/Forge [cite: 22]

[cite_start]I engineered a functional PoC to simulate the attack vector in a local environment[cite: 15, 22].

• [cite_start]Performance: The exploit was optimized for high-frequency execution, achieving a successful run in 1.72ms[cite: 16, 23].
• Outcome: Validated critical logic failure in position management.

[cite_start]The vulnerability was reported directly to the protocol's security team to ensure private remediation and protect user funds[cite: 17, 24].
