{"id":"CVE-2026-43893","state":"PUBLISHED","title":"exiftool-vendored: Argument injection via newline characters in tag names","description":"exiftool-vendored provides cross-platform Node.js access to ExifTool. Prior to 35.19.0, exiftool-vendored starts ExifTool in -stay_open True -@ - mode, where arguments are read from stdin one per line. In affected versions, several caller-supplied strings were interpolated into ExifTool arguments without rejecting line delimiters. A newline or carriage return inside one of those strings could split a single intended argument into multiple ExifTool arguments, allowing argument injection. The fix also rejects NUL bytes as unsafe control characters. Applications that pass attacker-controlled strings to affected APIs may allow an attacker to make ExifTool read files accessible to the ExifTool process, or write output to attacker-chosen file system paths accessible to that process. No remote code execution has been demonstrated. This vulnerability is fixed in 35.19.0.","publishedAt":"2026-05-11T20:59:14.560Z","updatedAt":"2026-05-12T12:54:40.823Z","severity":{"score":8.2,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["photostructure exiftool-vendored.js"],"affected":[{"vendor":"photostructure","product":"exiftool-vendored.js","versions":[{"version":"< 35.19.0","status":"affected"}]}],"references":["https://github.com/photostructure/exiftool-vendored.js/security/advisories/GHSA-cw26-7653-2rp5"],"weaknesses":["CWE-88"],"ingestedAt":"2026-10-29T20:11:57.932Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/43xxx/CVE-2026-43893.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-43893","state":"PUBLISHED","datePublished":"2026-05-11T20:59:14.560Z","dateUpdated":"2026-05-12T12:54:40.823Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-04T15:17:09.330Z"},"containers":{"cna":{"title":"exiftool-vendored: Argument injection via newline characters in tag names","descriptions":[{"lang":"en","value":"exiftool-vendored provides cross-platform Node.js access to ExifTool.
