Does this matter?

Lower severity and a low EPSS score (0.38%). Track it; it rarely justifies an emergency change on its own.

Description

Poweradmin is a web-based DNS administration tool for PowerDNS server. Versions prior to 4.2.4 and 4.3.3 are vulnerable to CSV Injection (Formula Injection) in its log export functionality. User-controlled data — specifically the username field — is written to exported CSV files without sanitizing formula trigger characters (=, +, -, @). When an administrator exports activity logs and opens the resulting CSV in a spreadsheet application (Microsoft Excel, LibreOffice Calc, Google Sheets), any formula stored in a username is executed by the application. This can be used for phishing attacks against administrators or data exfiltration. Versions 4.2.4 and 4.3.3 patch the issue.
