CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in Bridge - Creative Multipurpose WordPress Theme < 11.2 takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Bridge - Creative Multipurpose WordPress Theme the fix is 11.2: builds < 11.2 are affected, anything from 11.2 onward is not.
Remediation
Update to version 11.2, or a newer patched version
