{"id":"CVE-2026-43893","aliases":["GHSA-cw26-7653-2rp5"],"url":"https://o3.security/vulnerability/CVE-2026-43893","summary":"exiftool-vendored: Argument injection via newline characters in tag names","details":"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.","published":"2026-05-11T20:59:14.560Z","modified":"2026-08-07T11:31:23.648937761Z","cvss":{"score":8.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"exiftool-vendored","fixedVersion":"35.19.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43893.json"},{"type":"ADVISORY","url":"https://github.com/photostructure/exiftool-vendored.js/security/advisories/GHSA-cw26-7653-2rp5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43893"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:31:23.648937761Z"}}
