MediumDomain ownership ambiguity enabled by inconsistent management of tokenid when expired domains are repurchasedbrother id audit · Cairo Security Clan · 24 Dec 2024Fixed
Once an expired domain is repurchased, it can still be transferred using its old tokenid due to the contract not updating or clearing the old _token_id_to_domain mapping. This allows the previous owner to transfer the domain to another address without the current owner's consent, essentially renewing the domain at the expense of the current owner's purchase. Consider implementing a mechanism to maintain unique tokenids for each domain, even when repurchased after expiration.
