Description Dhananjay Arunesh 2019-02-20 13:22:27 UTC
WordPress before 4.9.9 and 5.x before 5.0.1 allows remote code execution because
an _wp_attached_file Post Meta entry can be changed to an arbitrary string, such
as one ending with a .jpg?file.php substring. An attacker with author privileges
can execute arbitrary code by uploading a crafted image containing PHP code in
the Exif metadata. Exploitation can leverage CVE-2019-8943.
