High CVSS 8.8
CVE-2026-14489
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.
What this means
- Exposure
- Exploitable remotely over the network, with an ordinary user account and with no action from the victim.
- Impact
- An attacker can read sensitive data, modify or destroy data and take the service offline.
- Weakness
- Upload accepts a dangerous file type, often one the server will execute.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
