CVE-2019-8942

Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 82.7%, higher than 100% of all known CVEs. Patch or mitigate before the next change window.
Description
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.
