What is known

The JSON Options WordPress plugin through 0.0.4 does not have any capability check or nonce verification on one of its actions, which runs on every request and is available to unauthenticated users, allowing them to update arbitrary WordPress options. This can be leveraged to enable user registration and set the default role to administrator, leading to privilege escalation and full site takeover.

Business impact

Successful exploitation of CVE-2026-75860, 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.
