Deeper analysis
A remote code execution vulnerability tracked as CVE-2018-7602 affects multiple subsystems of Drupal 7.x and 8.x. Rated 9.8 on CVSS 3.1 with vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H and linked to CWE-94, the flaw permits exploitation of several attack vectors that can result in full site compromise.
Remote attackers can trigger the issue without authentication or user interaction, obtaining arbitrary code execution that impacts confidentiality, integrity, and availability. The vulnerability is directly related to the earlier Drupal core remote code execution flaw described in SA-CORE-2018-002.
Security advisories, including Drupal SA-CORE-2018-004 along with Debian DSA-4180 and LTS announcements, point to the availability of patches that remediate the issue in supported releases.
Both CVE-2018-7602 and the associated SA-CORE-2018-002 are confirmed to be under active exploitation in the wild.

Directly requires timely application of vendor patches that remediate the Drupal RCE flaw before exploitation succeeds.
Enforces validation of all untrusted input, blocking the code-injection vectors (CWE-94) that enable unauthenticated RCE.
Boundary-protection mechanisms such as WAF rules can filter malicious requests targeting the Drupal subsystems before they reach the vulnerable code.
