An issue was discovered in the Real-Time Find and Replace plugin before 4.0.2 for WordPress. The far_options_page function did not do any nonce verification, allowing for requests to be forged on behalf of an administrator. The find and replace rules could be updated with malicious JavaScript, allowing for that be executed later in the victims browser.
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
