CVE-2026-107699: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in tzwm ppt2png
Description
ppt2png versions up to 0.0.6 contain an OS command injection vulnerability. This flaw allows attackers to execute arbitrary operating system commands by supplying unsanitized input or output path arguments. The vulnerability arises from improper neutralization of special elements in file names passed to child_process.exec() in ppt2png.js, enabling command execution with Node.js process privileges. The CVSS 4.0 score is 9.3, indicating a critical severity level.

Technical Analysis
CVE-2026-107699 is an OS command injection vulnerability in the ppt2png package (versions up to 0.0.6). The vulnerability occurs because the software uses unsanitized input or output path arguments in calls to child_process.exec() within ppt2png.js. Attackers can append shell metacharacters such as ';' to file names, causing arbitrary OS commands to be executed with the privileges of the Node.js process running ppt2png.
Potential Impact
Successful exploitation allows unauthenticated attackers to execute arbitrary operating system commands on the host running ppt2png, potentially leading to full system compromise depending on the Node.js process privileges. The vulnerability has a critical CVSS 4.0 score of 9.3, reflecting high impact and ease of exploitation without user interaction or privileges.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid using vulnerable versions of ppt2png or do not process untrusted input with ppt2png. Implement input validation and sanitization on file path arguments to prevent injection of shell metacharacters.
