{"id":"CVE-2026-47693","state":"PUBLISHED","title":"Poweradmin: CSV Injection in log export endpoints allows formula execution in spreadsheet applications","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.","publishedAt":"2026-06-23T22:07:25.569Z","updatedAt":"2026-06-24T14:46:24.461Z","severity":{"score":6.9,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:L/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["poweradmin poweradmin"],"affected":[{"vendor":"poweradmin","product":"poweradmin","versions":[{"version":"< 4.2.4","status":"affected"},{"version":">= 4.3.0, < 4.3.3","status":"affected"}]}],"references":["https://github.com/poweradmin/poweradmin/security/advisories/GHSA-3h6h-67x3-cv5x","https://github.com/poweradmin/poweradmin/releases/tag/v4.2.4","https://github.com/poweradmin/poweradmin/releases/tag/v4.3.3"],"weaknesses":["CWE-1236"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/47xxx/CVE-2026-47693.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-47693","state":"PUBLISHED","datePublished":"2026-06-23T22:07:25.569Z","dateUpdated":"2026-06-24T14:46:24.461Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-19T21:18:20.403Z"},"containers":{"cna":{"title":"Poweradmin: CSV Injection in log export endpoints allows formula execution in spreadsheet applications","descriptions":[{"lang":"en","value":"Poweradmin is a web-based DNS administration tool for PowerDNS server.
