{"id":"CVE-2026-47693","aliases":["GHSA-3h6h-67x3-cv5x"],"url":"https://o3.security/vulnerability/CVE-2026-47693","summary":"Poweradmin: CSV Injection in log export endpoints allows formula execution in spreadsheet applications","details":"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.","published":"2026-06-23T22:07:25.569Z","modified":"2026-08-12T03:51:45.758332157Z","cvss":{"score":6.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:L/A:N"},"epss":{"score":0.00375,"percentile":0.30538,"asOf":"2026-09-02"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"poweradmin/poweradmin","fixedVersion":"4.2.4"},{"ecosystem":"Packagist","name":"poweradmin/poweradmin","fixedVersion":"4.3.3"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/poweradmin/poweradmin/releases/tag/v4.2.4"},{"type":"WEB","url":"https://github.com/poweradmin/poweradmin/releases/tag/v4.3.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47693.json"},{"type":"ADVISORY","url":"https://github.com/poweradmin/poweradmin/security/advisories/GHSA-3h6h-67x3-cv5x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47693"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:45.758332157Z"}}
