Summary

CVE-2026-28134 is a high-severity Code Injection (CWE-94) vulnerability. Its CVSS base score is 8.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 14.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 RA-5 (Vulnerability Monitoring and Scanning) and SI-10 (Information Input Validation).

Deeper analysis

CVE-2026-28134 is an Improper Control of Generation of Code ('Code Injection') vulnerability in the Crocoblock JetEngine WordPress plugin (jet-engine) that allows Remote Code Inclusion. This issue affects JetEngine versions from n/a through 3.7.2 and has a CVSS v3.1 base score of 8.5 (AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H), mapped to CWE-94.

The vulnerability can be exploited by a low-privileged remote attacker (PR:L) over the network (AV:N) with high attack complexity (AC:H) and no user interaction (UI:N). Successful exploitation achieves high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H) with changed scope (S:C), enabling remote code execution.

Patchstack has published an advisory detailing the vulnerability in the WordPress JetEngine plugin version 3.7.2, available at https://patchstack.com/database/Wordpress/Plugin/jet-engine/vulnerability/wordpress-jetengine-plugin-3-7-2-remote-code-execution-rce-vulnerability?_s_id=cve.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

T1059.004 Unix Shell Execution

Adversaries may abuse Unix shell commands and scripts for execution.

T1505.003 Web Shell Persistence

Adversaries may backdoor web servers with web shells to establish persistent access to systems.

Why these techniques?

RCE via code injection in public-facing WordPress plugin directly enables T1190 for initial access; arbitrary code execution maps to Unix shell interpreter (T1059.004); remote code inclusion facilitates web shell deployment (T1505.003).
