AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N

Name of the Vulnerable Software and Affected Versions WordPress versions prior to 5.0.4

Description The issue allows for Path Traversal in the wp crop image() function. An attacker with privileges to crop an image can write the output image to an arbitrary directory via a filename containing two image extensions and ../ sequences. For example, a filename ending with the .jpg?/../../file.jpg substring can be used.

Recommendations For WordPress versions prior to 5.0.4, update to version 5.0.4 or later to resolve the issue. As a temporary workaround, consider restricting the wp crop image() function to prevent arbitrary directory writing until a patch is available.
