CVE-2026-81090: CWE-434 Unrestricted Upload of File with Dangerous Type in Gpx2Graphics
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.
AI Analysis
Technical Summary
CVE-2026-81090 describes a vulnerability in the Gpx2Graphics WordPress plugin versions up to 0.3. The plugin does not perform Cross-Site Request Forgery (CSRF) checks when handling file uploads and fails to validate the type of uploaded files. This combination allows an attacker to exploit a logged-in administrator by forcing them to upload arbitrary files, including executable PHP scripts, via a CSRF attack. Successful exploitation can result in remote code execution on the affected system.
Potential Impact
An attacker can leverage this vulnerability to execute arbitrary code on the server hosting the vulnerable plugin by uploading malicious files disguised as legitimate uploads. This can compromise the integrity and confidentiality of the affected system and potentially lead to full system compromise.
Mitigation Recommendations
No official patch or fix is currently documented. Users should immediately restrict administrative access and avoid using the vulnerable plugin version. Applying strict access controls and disabling file uploads in the plugin until a fix is available is recommended. Monitor the vendor advisory for updates regarding an official fix or patch.
