CVE-2026-14553: CWE-434 Unrestricted Upload of File with Dangerous Type in zportals
CVE-2026-14553 is a vulnerability in the zportals WordPress plugin before version 6.3.4 that allows authenticated users with Subscriber or higher privileges to upload arbitrary PHP files. This occurs because the plugin does not properly validate uploaded files, relying on client-supplied content types and preserving original file extensions. Exploiting this flaw can lead to remote code execution on the affected system.
AI Analysis
Technical Summary
The zportals WordPress plugin versions prior to 6.3.4 suffer from improper validation of uploaded files. The plugin trusts the client-supplied content type and preserves the original file extension, enabling any authenticated user with at least Subscriber privileges to upload arbitrary PHP files. This vulnerability corresponds to CWE-434 (Unrestricted Upload of File with Dangerous Type) and can be exploited to achieve remote code execution on the server hosting the plugin.
Potential Impact
An attacker with authenticated access as a Subscriber or higher can upload malicious PHP files, leading to remote code execution. This compromises the confidentiality, integrity, and availability of the affected system and potentially the broader environment hosting the WordPress instance.
Mitigation Recommendations
No official patch or remediation guidance is currently available. Users should monitor the vendor advisory for updates and apply the official fix once released. Until then, restricting upload permissions or disabling the plugin may reduce risk.
