CVE-2019-9787 (opens in a new tab)How to fix?
Upgrade Debian:9 wordpress to version 4.7.5+dfsg-2+deb9u6 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream wordpress package and not the wordpress package as distributed by Debian.
See How to fix? for Debian:9 relevant fixed versions and status.
WordPress before 5.1.1 does not properly filter comment content, leading to Remote Code Execution by unauthenticated users in a default configuration. This occurs because CSRF protection is mishandled, and because Search Engine Optimization of A elements is performed incorrectly, leading to XSS. The XSS results in administrative access, which allows arbitrary changes to .php files. This is related to wp-admin/includes/ajax-actions.php and wp-includes/comment.php.
