HIGH CVE-2026-81090 Received

Gpx2Graphics upload CSRF can make an administrator install PHP

Gpx2Graphics through 0.3 neither verifies a CSRF token nor validates file type in its upload flow. An attacker can trick a logged-in administrator into submitting a forged upload that stores PHP and leads to remote code execution. The authoritative export does not identify the upload action, field, destination, or whether the file is directly web-accessible.

This CVE was published Sep 12, 2026 and is one of 1 known issue for this plugin.

Update, patch or deactivate.

No fixed release is confirmed in the authoritative export. Deactivate the plugin and inspect its upload location. The application-level fix must require a nonce and administrative capability, strictly validate content and extension, generate server-side names, and keep uploads outside executable web paths.

No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Technical description

The Gpx2Graphics WordPress plugin through 0.3 does not perform a CSRF check when handling file uploads, nor validate the type of the uploaded file, allowing attackers to make a logged-in administrator upload arbitrary files such as PHP via a CSRF attack, leading to Remote Code Execution.
