BCH does not support segwit. This means that any unspent transaction outputs locked to a wrapped segwit output (P2SH-P2WSH) will appear as an "anyone-can-spend" output within the ruleset of BCH. Spending such an output will cause a transaction to be non-standard, as it will cause an element to be leftover on the stack, which means that miners generally don't include such transactions into blocks.


However, to create such an “anyone-can-spend” transaction, one still needs to know the redeem script for the address.


The redeem script is only known to the creator of the address until someone spends funds from the address for the first time.


So, when someone receives funds to a wrapped segwit address that has been previously used, someone would be able to create such a transaction and get it mined (with the support of a miner).
