CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2018-7602 is a critical-severity Code Injection (CWE-94) vulnerability in Drupal Drupal. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked in the top 0.1% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).
PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.
