CosmWasm Security Spotlight is intended to be a series of medium posts about vulnerabilities found in audits of CW smart contracts. It would be a good starting point for anyone looking to get into CW contracts audits or to develop more secure smart contracts.
In addition, I created some hands-on labs so the reader can practice their bug-hunting skills in easy targets. This series is being published in collaboration with Oak Security.
