The MapSVG plugin for WordPress contains an improper input validation vulnerability in the SVGFile constructor that affects all versions up to and including 8.14.0. This flaw allows authenticated users with Administrator-level access or higher to upload arbitrary files due to missing file type validation. Exploitation of this vulnerability could lead to remote code execution on the affected server. The vulnerability has a high severity rating with a CVSS score of 7.2. No official patch or remediation guidance has been provided at this time.
AI Analysis
Technical Summary
CVE-2026-1771 is an improper input validation vulnerability (CWE-20) in the MapSVG WordPress plugin (versions <=8.14.0). The issue arises from an incorrect conditional check in the SVGFile constructor that bypasses file type validation, enabling authenticated administrators to upload arbitrary files to the server. This arbitrary file upload can potentially be leveraged to achieve remote code execution. The vulnerability has a CVSS 3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H), indicating network exploitable with low attack complexity but requiring high privileges.
Potential Impact
Authenticated users with Administrator-level privileges can upload arbitrary files to the server hosting the vulnerable MapSVG plugin. This can lead to remote code execution, compromising confidentiality, integrity, and availability of the affected system. The vulnerability affects all versions up to and including 8.14.0 of the plugin.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Administrator-level access to trusted users only and monitor for suspicious file uploads related to the MapSVG plugin. Avoid using affected versions in production environments if possible.
