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.","state":"PUBLISHED","assigner":"GitHub_M","published_at":"2026-06-23 23:16:49","updated_at":"2026-06-23 23:16:49"},"problem_types":["CWE-1236","CWE-1236 CWE-1236: Improper Neutralization of Formula Elements in a CSV File"],"metrics":[{"version":"3.1","source":"security-advisories@github.com","type":"Secondary","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","data":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:L/A:N","baseScore":6.9,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"REQUIRED","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"LOW","availabilityImpact":"NONE"}},{"version":"3.1","source":"CNA","type":"DECLARED","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","data":{"attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"NONE","baseScore":6.9,"baseSeverity":"MEDIUM","confidentialityImpact":"HIGH","integrityImpact":"LOW","privilegesRequired":"HIGH","scope":"CHANGED","userInteraction":"REQUIRED","vectorString":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:L/A:N","version":"3.1"}}],"references":[{"url":"https://github.com/poweradmin/poweradmin/security/advisories/GHSA-3h6h-67x3-cv5x","name":"https://github.com/poweradmin/poweradmin/security/advisories/GHSA-3h6h-67x3-cv5x","refsource":"security-advisories@github.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://github.com/poweradmin/poweradmin/releases/tag/v4.3.3","name":"https://github.com/poweradmin/poweradmin/releases/tag/v4.3.3","refsource":"security-advisories@github.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://github.com/poweradmin/poweradmin/releases/tag/v4.2.4","name":"https://github.com/poweradmin/poweradmin/releases/tag/v4.2.4","refsource":"security-advisories@github.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-47693","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47693","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[{"source":"CNA","vendor":"poweradmin","product":"poweradmin","version":"affected < 4.2.4","platforms":[]},{"source":"CNA","vendor":"poweradmin","product":"poweradmin","version":"affected >= 4.3.0, < 4.3.3","platforms":[]}],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"containers":{"cna":{"affected":[{"product":"poweradmin","vendor":"poweradmin","versions":[{"status":"affected","version":"< 4.2.4"},{"status":"affected","version":">= 4.3.0, < 4.3.3"}]}],"descriptions":[{"lang":"en","value":"Poweradmin is a web-based DNS administration tool for PowerDNS server.
