Incident Overview
On January 30, 2026, Revert Finance's newly launched Aerodrome Lend vault on Base suffered a $50,101 exploit when an attacker exploited a missing safety constraint in the staking/management layer, allowing them to withdraw liquidity from a collateralized NFT position while it was still backing an active loan.
The vulnerability existed in an execution pathway within the GaugeManager contract that allowed position owners to modify staked, collateralized NFT positions without proper vault oversight. The attacker flash-loaned funds from Morpho, minted an Aerodrome Slipstream concentrated liquidity NFT position, and deposited it as collateral into the Aerodrome Lend vault. After borrowing USDC against this collateral, the position was staked through the vault's staking flow.
The attacker then exploited the GaugeManager's utility contract execution path, which temporarily unstaked the NFT to perform position-management operations. Because this pathway lacked constraints preventing modification of debt-backed positions, the attacker withdrew all liquidity from the NFT and routed it to their address, leaving the vault holding a worthless NFT shell while the loan remained outstanding. The flash loan was repaid and the borrowed USDC became profit.
A second attacker replicated the exploit 58 minutes later.

What Auditors Should Check
If you're auditing a protocol with similar architecture to Revert Lend, these are the critical security checks that could have prevented this incident (January 2026).
- Verify all logic paths related to Staked Collateral Exploit / Other are guarded by proper access controls and input validation
- Review privileged functions (owner, admin, governance) for potential abuse vectors - centralization risks should be documented and bounded with timelocks or multi-sigs
