CVE-2025-13062
Published: 15 January 2026
Summary
CVE-2025-13062 is a high-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Wordpress (inferred from references). Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 39.2th 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).
Deeper analysis
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.

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.
Enforces restrictions on information inputs to limit file types and prevent unrestricted uploads of arbitrary files that bypass sanitization.
Requires timely flaw remediation through patching the vulnerable Supreme Modules Lite plugin to fix the file upload validation defect.
