Technical description

The Webinfos WordPress plugin through 1.2 does not validate the type or name of uploaded files, nor restrict the upload action with any authentication, capability, or nonce check, allowing unauthenticated attackers to upload arbitrary files (including PHP) to a web-accessible directory, leading to remote code execution on servers that execute PHP from the uploads path.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
