On June 2023, MIMSpell was exploited in a arbitrary call, resulting in approximately $17K in losses. That makes the MIMSpell exploit the 345th largest DeFi incident out of 690 documented in our archive.
Attack Mechanics: How the MIMSpell Arbitrary Call Played Out
Exploit Class Applied to MIMSpell
The MIMSpell incident on June 20, 2023 is classified as a Arbitrary Call. The contract executes an external call with attacker-controlled target or calldata, letting them impersonate the contract. In the full archive, MIMSpell is 1 of 21 documented arbitrary call incidents.
MIMSpell in Context
At $17K, the MIMSpell exploit is a minor (<$1M) event compared to the largest same-class incident in our archive — Seneca (2024) at $6M.
Prior Arbitrary Call Before MIMSpell
The nearest arbitrary call incident before MIMSpell was – RevertFinance, 122 days earlier on February 18, 2023 ($30K lost). The same exploit class surfaced again within the arbitrary call attack surface.
MIMSpell Vulnerability Signature
The primary source categorises the MIMSpell exploit specifically as “Arbitrary External Call Vulnerability”. This narrower label is entity-specific: it reflects how the MIMSpell contract failed, rather than the broad arbitrary call pattern alone.
