Description Dhananjay Arunesh 2019-02-20 12:57:45 UTC

WordPress through 5.0.3 allows Path Traversal in wp_crop_image(). An attacker
(who has privileges to crop an image) can write the output image to an arbitrary
directory via a filename containing two image extensions and ../ sequences, such
as a filename ending with the .jpg?/../../file.jpg substring.
