typedefabcd1234ntd/cve-2026-19500-pocProof-of-concept for CVE-2026-19500, a DoS vulnerability in the SureForms WordPress plugin that exhausts server resources via oversized key-value form submissions.
Sureforms is vulnerable to a DOS vulnerability , when attacker can submit unlimited key-value pair, leads to resource exhaustion and the administrator can not watch entries temporary.
Submit the Form which is made by Sureforms plugin, and then create large amount of key-value pair, with large size of content in a pair and then submitted. Just need a few times for submit it and admin cannot see the entries.
You can also run this Poc a few times and the vulnerability will be exploited.
Update to the latest version (2.12.3 or newer), which have partitially patched the issue
