Assuming no strong replay protection, all transactions using UTXOs valid on both chains will be vulnerable to replay attacks.
Replay attacks get this name because they’re carried out by a hacker who essentially replays an authentication session to trick a computer into granting them access. Any retransmission of network data transmissions for the sake of unauthorized access to a system would fall under this type of attack.

Using this approach, an attacker can fraudulently authenticate himself to a system though he is not authorized to do so. A replay attack is a type of security issue in which a third party intercepts data transmissions with the purpose of making use of that data in some manner. One of the more common examples of a replay attack involves capturing and making copies of login information. A replay attack occurs when an attacker copies a stream of messages between two parties and replays the stream to one or more of the parties. Unless mitigated, the computers subject to the attack process the stream as legitimate messages, resulting in a range of bad consequences, such as redundant orders of an item. During replay attacks the intruder sends to the victim the same message as was already used in the victim's communication. The message is correctly encrypted, so its receiver may treat is as a correct request and take actions desired by the intruder.
