What is known
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.
Business impact
Successful exploitation of CVE-2026-12872, a critical vulnerability (CVSS 9.8) affecting the affected product, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.
Recommended administrator action
Confirm whether the affected product is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
