Name of the Vulnerable Software and Affected Versions Halo version 1.1.3

Description The issue allows for arbitrary file reading. It occurs in an interface that reads files, where a directory traversal check is performed on the input path parameter. However, this check can be bypassed using the startsWith function.

Recommendations For Halo version 1.1.3, consider restricting access to the file reading interface until a proper fix is implemented to prevent directory traversal attacks. As a temporary workaround, review and validate all input paths to ensure they do not bypass the directory traversal check.
