CVSS 7.400000095367432 HIGH
A flaw was found in PostCSS. A remote attacker can exploit this vulnerability by providing a specially crafted sourceMappingURL when a specific configuration (the 'from' parameter) is not set. This can cause the application to read and expose unintended source-map files, potentially revealing sensitive information about the application's source code.
