This vulnerability in the Radio Buttons and Swatches for WooCommerce plugin (versions <= 1.1.20) allows reflected Cross-site Scripting (XSS) due to improper input neutralization during web page generation. An attacker could craft a malicious URL or input that, when processed by the plugin, causes execution of arbitrary scripts in the context of the victim's browser. The CVSS 3.1 base score is 7.1, indicating high severity with network attack vector, low attack complexity, no privileges required, user interaction required, and impacts to confidentiality, integrity, and availability.

Successful exploitation can lead to execution of arbitrary scripts in users' browsers, potentially resulting in theft of sensitive information, session hijacking, or other malicious actions affecting confidentiality, integrity, and availability of user data. The reflected nature means the attack requires user interaction (e.g., clicking a crafted link). There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution with untrusted input and consider temporary mitigations such as input validation or disabling the affected plugin if feasible.
