ppt2png 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.

dot-access 0.0.3 through 1.0.0 contains a code injection vulnerability that allows remote attackers to execute JavaScript by supplying crafted paths to get(). The path is concatenated into a new Function body in index.js, so attackers can reach constructor.constructor to load child process and run operating system commands in the Node.js process.

dot-access through 1.0.0 contains a prototype pollution vulnerability that allows attackers to modify Object.prototype by supplying a crafted dotted path to set(). Attackers controlling the path, such as through user-supplied field names, can use proto segments to inject properties into all objects, altering authorization flags and option defaults or crashing the process.

@enmaso/node-convert through 1.0.0 contains an OS command injection vulnerability in convert.js that allows attackers to execute shell commands via unsanitized filepath and convertTo arguments. Attackers can inject shell metacharacters or a single quote into the ImageMagick command run by child process.exec() to execute operating system commands with Node.js process privileges.

The image optimizer Ruby gem 1.3.0 through 1.9.0 contains an OS command injection vulnerability in ImageOptimizer#identify format that allows attackers to execute commands by supplying a crafted image path when the identify option is enabled. Attackers controlling the path, such as an uploaded file name, can append shell metacharacters like ';' that are executed via Ruby backticks with the Ruby process privileges.
