Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 40.8th 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 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly addresses the insufficient file type validation by requiring the system to check validity of all inputs, including uploaded files, to block arbitrary dangerous types like double-extension JSON.

SI-9 Information Input Restrictions good match

prevent

Enforces restrictions on information inputs to limit file types and prevent unrestricted uploads of arbitrary files that bypass sanitization.

SI-2 Flaw Remediation good match

prevent

Requires timely flaw remediation through patching the vulnerable Supreme Modules Lite plugin to fix the file upload validation defect.

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.

Why these techniques?

Arbitrary file upload vulnerability in a public-facing WordPress plugin allows authenticated low-privilege attackers to upload malicious files leading to remote code execution, directly mapping to exploitation of public-facing applications.

Confidence: HIGH · MITRE ATT&CK Enterprise v19.0

NVD Description

The Supreme Modules Lite plugin for WordPress is vulnerable to arbitrary file upload in all versions up to, and including, 2.5.62. This is due to insufficient file type validation detecting JSON files, allowing double extension files to bypass sanitization while…

being accepted as a valid JSON file. This makes it possible for authenticated attackers, with author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

Deeper analysisAI

CVE-2025-13062 is an arbitrary file upload vulnerability in the Supreme Modules Lite plugin for WordPress, affecting all versions up to and including 2.5.62. The issue stems from insufficient file type validation that fails to properly detect JSON files, permitting double extension files to bypass sanitization while being accepted as valid JSON uploads. This flaw is classified under CWE-434 (Unrestricted Upload of File with Dangerous Type) and carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

Authenticated attackers with author-level access or higher can exploit this vulnerability over the network with low complexity and no user interaction required. By uploading arbitrary files to the affected WordPress site's server, they can potentially achieve remote code execution, granting high levels of confidentiality, integrity, and availability impact.

Mitigation is addressed in the plugin's patch via WordPress Trac changeset 3423427 at https://plugins.trac.wordpress.org/changeset/3423427/supreme-modules-for-divi, which security practitioners should apply by updating to a fixed version.
