CVE-2025-13065: CWE-434 Unrestricted Upload of File with Dangerous Type in brainstormforce Starter Templates – AI-Powered Templates for Elementor & Gutenberg
The Starter Templates plugin for WordPress is vulnerable to arbitrary file upload in all versions up to, and including, 4.4.41. This is due to insufficient file type validation detecting WXR files, allowing double extension files to bypass sanitization while being accepted as a valid WXR 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.
AI Analysis
Technical Summary
CVE-2025-13065 is a file upload vulnerability in the Starter Templates plugin for WordPress (versions up to 4.4.41). The plugin fails to properly validate file types, specifically allowing double extension files to be treated as valid WXR files. This flaw enables authenticated users with author-level privileges or higher to upload arbitrary files to the server, potentially leading to remote code execution. The vulnerability is categorized under CWE-434 (Unrestricted Upload of File with Dangerous Type) and has a CVSS 3.1 base score of 8.8, indicating a high impact on confidentiality, integrity, and availability.
Potential Impact
An attacker with author-level access or above can upload arbitrary files to the web server due to improper file type validation. This can lead to remote code execution, compromising the affected WordPress site’s confidentiality, integrity, and availability. The high CVSS score reflects the critical nature of this vulnerability in a widely used plugin, potentially allowing significant control over the affected system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
