CVE-2026-43893— exiftool-vendored 参数注入漏洞

exiftool-vendored: Argument injection via newline characters in tag names

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.

参数注入或修改

exiftool-vendored 参数注入漏洞

exiftool-vendored是PhotoStructure开源的一款跨平台图片元数据读写工具。 exiftool-vendored 35.19.0之前版本存在参数注入漏洞，该漏洞源于在-stay_open True -@ -模式下启动ExifTool时，多个调用者提供的字符串被插值到ExifTool参数中而未拒绝行分隔符，导致换行符或回车符可将单个预期参数拆分为多个ExifTool参数，允许参数注入，应用程序将攻击者控制的字符串传递给受影响的API可能允许攻击者使ExifTool读取可访问的文件或写
