HashBrown CMS through 1.4.6 contains an OS Command Injection vulnerability (CWE-78) in the Git deployer component. GitDeployer.pullRepo in src/Server/Entity/Deployer/GitDeployer.js executes AppService.exec, interpolating the configured branch value directly into a shell command with no escaping.

HashBrown CMS - OS Command Injection in Media Upload Thumbnail Generation

HashBrown CMS through 1.4.6 contains an OS Command Injection vulnerability (CWE-78) in the media upload thumbnail generation routine. Media.generateThumbnail in src/Server/Entity/Resource/Media.js builds a temporary file path as 'thumbnail' + Path.extname(filename) and passes it, unescaped, into a shell command executed via AppService.exec ('convert ' + tempFile + ...).
