Cross-Site Request Forgery (CSRF)
The FormBuilder WordPress plugin through 1.08 does not have CSRF checks in place when creating/updating and deleting forms, and does not sanitise as well as escape its form field values. As a result, attackers could make logged in admin update and delete arbitrary forms via a CSRF attack, and put Cross-Site Scripting payloads in them.
CWE-352 - Cross-Site Request Forgery (CSRF)
Cross-Site Request Forgery (CSRF) is a vulnerability that allows an attacker to make arbitrary requests in an authenticated vulnerable web application and disrupt the integrity of the victim’s session. The impact of a successful CSRF attack may range from minor to severe, depending upon the capabilities exposed by the vulnerable application and privileges of the user. An attacker may force the user to perform state-changing requests like transferring funds, changing their email address or password etc. However, if an administrative level account is affected, it may compromise the whole web application and associated sensitive data.
