Does this matter?

Lower severity and a low EPSS score (0.14%). Track it; it rarely justifies an emergency change on its own.

Description

HCL BigFix Service Management (SM) does not adequately sanitize or safely render spreadsheet files (CSV, XLS, XLSX) before processing or distributing them. An attacker could populate data fields which, when saved to a CSV file, may attempt information exfiltration or other malicious activity when automatically executed by the spreadsheet software. Note that current versions of Excel warn users of untrusted content.
