Technical details

A path traversal vulnerability in Ghost's theme translation file loading mechanism allows authenticated administrators with high privileges to access arbitrary JSON files on the server by crafting malicious locale settings. The vulnerability exists because the locale parameter is not properly sanitized before being used to construct file paths. The fix in version 6.64.0 restricts file loading to the active theme directory.
