Depends on the AP, the controller and the firmware used.

AP to client and vice-versa can be encrypted using WPA2.

capwap Data DTLS can be used to encrypt AP to WLC and vice-versa.

For client encryption to AP check the SSID -> Security -> Layer 2 Security settings. If it's set to None, then the traffic is unencrypted. Static WEP is on paper an encryption, but has been cracked for many years and is actually worse now than no encryption. WPA2 or WPA3 are the current recommendations.

For CAPWAP encryption, go to Wireless -> select an AP -> Advanced tab and check of the Data Encryption is checked. If unchecked, then the traffic between AP and WLC is unencrypted.
