CVE-2026-107699
CRITICAL 9.3ppt2png through 0.0.6 contains an OS command injection vulnerability that allows attackers to execute operating system commands by supplying unsanitized input or output path arguments. Attackers can append shell metacharacters such as ';' to file names passed to child_process.exec() in ppt2png.js, running commands with Node.js process privileges.
Severe if exploited (CVSS 9.3), but no known exploitation and low modeled probability. Patch on a normal cadence.
