The vulnerability allows unauthenticated attackers to exploit the POST /api/templates/preview endpoint in affected versions prior to 0.30.0, enabling them to perform path traversal attacks and access arbitrary files on the server. This could lead to the exposure of sensitive information, such as credentials and configuration files, through the JSON response. Organizations using these affected versions should prioritize patching to mitigate the risk of unauthorized data access.
