CVE-2025-11498Network attack vector

Spreadsheet formula execution via unsanitized CSV fields

Published Oct 14, 2025 · Updated Oct 14, 2025

CSV formula injection in B&R Automation Runtime before 6.4 allows remote attackers to embed formulas in SDM-generated CSV files. SDM places hyperlink-controlled input into CSV fields without neutralizing spreadsheet formula elements. Exploitation requires network access to an SDM-enabled node, a user to follow a malicious link, and the resulting CSV to be opened manually, enabling formula execution in the spreadsheet user's security context.
