Miggo AIRoot Cause Analysis

The vulnerability is described as being in post.php, an example script that echoes POST data. The nuclei-template confirms this by targeting post.php. While the exact source code of post.php from the vulnerable version could not be fetched directly from the repository using common paths, the consistent reporting across the vulnerability description and the detection template provides high confidence that the post.php script itself is the vulnerable component. In PHP, a script file can be considered the entry point and thus would appear in logs or profiles if directly accessed.
