CVE-2026-47693 - Poweradmin: CSV Injection in log export endpoints allows formula execution in spreadsheet applications
Posted: Wed Jun 24, 2026 2:47 am
CVE ID: CVE-2026-47693
Published: June 23, 2026
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.
Severity: 6.9
