CVE-2026-1771: CWE-20 Improper Input Validation in oyatek MapSVG – Vector maps, Image maps, Google Maps
The MapSVG plugin for WordPress contains an improper input validation vulnerability in the SVGFile constructor that allows arbitrary file uploads. This affects all versions up to and including 8.14.0. The flaw arises from an incorrect conditional check that disables file type validation. Authenticated users with Administrator-level access or higher can exploit this to upload arbitrary files to the server, potentially enabling remote code execution. The vulnerability has a high severity rating with a CVSS score of 7.2. No official patch or remediation has been confirmed at this time.
AI Analysis
Technical Summary
CVE-2026-1771 describes an improper input validation vulnerability (CWE-20) in the MapSVG WordPress plugin up to version 8.14.0. The issue is due to a faulty conditional check in the SVGFile constructor that prevents proper file type validation, allowing authenticated administrators to upload arbitrary files. This can lead to remote code execution on the affected server. The vulnerability requires administrator privileges and does not involve user interaction. No vendor advisory or patch information is currently available.
Potential Impact
An attacker with administrator-level access can upload arbitrary files to the server hosting the vulnerable MapSVG plugin. This can result in remote code execution, compromising confidentiality, integrity, and availability of the affected system. The vulnerability is rated high severity with a CVSS 3.1 score of 7.2, reflecting network attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict administrator access to trusted users only and monitor for suspicious file uploads. Avoid granting unnecessary administrator privileges. Follow vendor communications closely for an official fix or update.
