What is CVE-2026-85642?
The Formidable Forms plugin for WordPress prior to version 7.0 is susceptible to an authentication bypass that compromises payment gateway verification. This vulnerability allows unauthenticated users to manipulate the timestamp for rate limiting, thereby exhausting the allotted attempts for legitimate users and leading to a denial of service in processing payments for the next 24 hours. This exploitation poses a significant risk to the reliability and functionality of online transactions on sites using this plugin.
Affected Version(s)
Formidable Forms 6.5 < 7.0
