CVE-2026-19501 SureForms CVE debrief

Who should care

Administrators and users of Brainstorm Force SureForms version <= 2.12.1, as well as security teams responsible for monitoring and mitigating potential threats related to CSV file imports and spreadsheet applications, should prioritize updating to a patched version to prevent potential exploitation. Additionally, security teams should review compensating controls for exposed systems while remediation is scheduled and verified, and track exceptions, retest remediated assets, and close the item only after evidence is documented.

Technical summary

The CSV export functionality in Brainstorm Force SureForms version <= 2.12.1 does not properly sanitize user-controlled form field names, allowing for the injection of spreadsheet formulas. When an administrator exports a CSV file containing maliciously crafted form field names and opens it in a vulnerable spreadsheet application, the formulas can be executed, potentially leading to remote code execution on the administrator's workstation. This vulnerability can be exploited by a remote attacker, and its successful exploitation could result in significant impact, including potential remote code execution.

Defensive priority

Administrators and users of Brainstorm Force SureForms version <= 2.12.1 should prioritize updating to a patched version to prevent potential exploitation.

Recommended defensive actions

• Update Brainstorm Force SureForms to a version greater than 2.12.1
• Administrators should exercise caution when opening CSV files exported from SureForms in spreadsheet applications
• Implement content security policies to restrict execution of macros or formulas in CSV files
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE-2026-19501 record indicates that the CSV export functionality in Brainstorm Force SureForms version <= 2.12.1 fails to neutralize spreadsheet formula characters in user-controlled form field names. This 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. Evidence is limited; further verification is recommended.
