CVE-2026-14489: CWE-434 Unrestricted Upload of File with Dangerous Type in globalprogramming WHMCS Bridge
The WHMCS Bridge plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the connect() function in all versions up to, and including, 6.9. This makes it possible for authenticated attackers, with Custom-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
AI Analysis
Technical Summary
CVE-2026-14489 describes an unrestricted file upload vulnerability (CWE-434) in the WHMCS Bridge WordPress plugin by globalprogramming. The flaw exists in the connect() function where file type validation is missing, allowing authenticated users with Custom-level privileges or above to upload arbitrary files. This can lead to remote code execution on the server hosting the plugin. The vulnerability affects all versions up to and including 6.9. No official patch or remediation level has been published yet, and no known exploits are reported in the wild.
Potential Impact
An attacker with authenticated access at Custom-level or higher can upload arbitrary files to the server, potentially leading to remote code execution. This compromises confidentiality, integrity, and availability of the affected system. The high CVSS score (8.8) reflects the critical impact of this vulnerability if exploited.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to users with Custom-level privileges or higher, and monitor for suspicious file uploads. Avoid granting unnecessary upload permissions to reduce risk.
