Description Robert Frohl 2019-02-20 10:22:14 UTC 
CVE-2019-8943

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.

Comment 1 Eric Schirra 2019-02-25 07:59:45 UTC 
Have done update to 5.1 in my home repo.
Before i push to devel i will test it.

But i don't know if CVE-2019-8943 is fixed, because it is plenty years
old and no entry found at wordpress itself.
