CVE-2026-43893 Details
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.
A vulnerability allowing argument injection has been identified in ExifTool-Vendored versions prior to 35.19.0. The issue arises because the application interpolates user-supplied strings into ExifTool arguments without properly sanitizing them, allowing newline or carriage return characters to split a single argument into multiple ones. This vulnerability could be exploited by applications that pass attacker-controlled strings to certain ExifTool APIs, potentially allowing an attacker to manipulate file reading or writing operations. The vulnerability has been fixed in version 35.19.0.
Users are advised to upgrade to ExifTool-Vendored version 35.19.0 or later. If an immediate upgrade is not possible, untrusted strings containing control characters should be rejected before being passed to the affected ExifTool APIs. This can be done using a simple TypeScript function that checks for unsafe characters.
