CVE-2026-19501

CSV export functionality in Brainstorm Force SureForms version, <= 2.12.1, fails to neutralize spreadsheet formula characters in user-controlled form field names before generating CSV exports, which allows a remote attacker to execute spreadsheet formulas on an administrator's workstation when the exported CSV file is opened in a vulnerable spreadsheet application.

What this means for your business

  • An attacker can use it remotely, over a network, without a login, but only after tricking someone into an action such as opening a file or a link.
  • FIRST's prediction model gives it a 0.5% chance of attack attempts being seen in the next 30 days, ranking above 38% of all known flaws.

What to do

  1. 1Ask your IT team or provider whether any of your systems use the affected product.
  2. 2If you do, follow the vendor's guidance. No patch reference has been published yet.
