Miggo AIRoot Cause Analysis

The vulnerability stems from insecure handling of uploaded images where EXIF data was not stripped. The patch in commit b592c86 modifies the image processing logic in plupload.php to explicitly re-save images using GD library functions (imagejpeg/imagepng/imagegif), which creates new images without EXIF data. The presence of these functions in the code without proper execution or implementation in versions <1.3 indicates the vulnerability. The diff shows the same GD functions were present but lacked the critical EXIF-stripping behavior before the patch, likely due to missing logic paths or improper configuration.
