CVE-2026-19500Public exploitNetwork attack vector

Service interrupt via unbounded entry submissions

Published Aug 18, 2026 · Updated Aug 19, 2026

Resource exhaustion in the Entries component in Brainstorm Force SureForms before 2.12.3 allows remote attackers to interrupt service via crafted form submissions. The Entries workflow accepts excessive numbers and sizes of user-controlled fields and then processes and renders that data without adequate limits, exhausting server resources and breaking the Entries view with HTTP 500 errors. No authentication is required where a public SureForms form is reachable, and the reported consequence is administrative lockout from the Entries interface rather than data disclosure or code execution.
