Attack Mechanics: How the CEXISWAP Access Control Played Out
Exploit Class Applied to CEXISWAP
The CEXISWAP incident on September 21, 2023 is classified as a Access Control. A privileged function lacks a proper authorisation check, letting an unauthorised caller execute it. In the full archive, CEXISWAP is 1 of 77 documented access control incidents.
CEXISWAP in Context
At $30K, the CEXISWAP exploit is a minor (<$1M) event compared to the largest same-class incident in our archive — Corkprotocol (2025) at $12M.
Prior Access Control Before CEXISWAP
The nearest access control incident before CEXISWAP was LeetSwap, 51 days earlier on August 1, 2023 ($630K lost). The same exploit class surfaced again within the access control attack surface.
CEXISWAP Vulnerability Signature
The primary source categorises the CEXISWAP exploit specifically as “Incorrect Access Control”. This narrower label is entity-specific: it reflects how the CEXISWAP contract failed, rather than the broad access control pattern alone.
