CVE-2026-43893: CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') in photostructure exiftool-vendored.js
A high-severity vulnerability (CVE-2026-43893) exists in photostructure's exiftool-vendored.js prior to version 35.19.0. The issue involves improper neutralization of argument delimiters, allowing attacker-controlled input containing newline or carriage return characters to inject additional arguments into ExifTool commands. This can cause ExifTool to read or write files accessible to its process based on attacker input. No remote code execution has been demonstrated. The vulnerability is fixed in version 35.19.0.
AI Analysis
Technical Summary
The exiftool-vendored.js library for Node.js, which provides access to ExifTool, improperly handles caller-supplied strings by interpolating them into ExifTool command arguments without rejecting line delimiters such as newline or carriage return characters. This allows an attacker to inject additional arguments into ExifTool commands, potentially causing ExifTool to read arbitrary files or write output to attacker-chosen file system paths accessible to the ExifTool process. The vulnerability is identified as CWE-88 (Improper Neutralization of Argument Delimiters). The fix in version 35.19.0 rejects unsafe control characters including NUL bytes to prevent this argument injection.
Potential Impact
An attacker who can supply input to the affected APIs may cause ExifTool to process unintended files or write output to arbitrary file paths accessible to the ExifTool process. This can lead to unauthorized disclosure or modification of files. The vulnerability does not enable remote code execution. There are no known exploits in the wild at this time.
Mitigation Recommendations
This vulnerability is fixed in exiftool-vendored.js version 35.19.0. Users should upgrade to version 35.19.0 or later to remediate this issue. Patch status is not explicitly stated beyond the fixed version; therefore, confirm remediation by upgrading to the fixed version. No other vendor advisory or temporary workaround is provided.
