Patch to version 1.8.1.759 or later where this vulnerability is fixed. Since the affected versions are prior to 1.8.1.759, upgrading the plugin to this version or newer will remediate the issue.

Description

The Surfer WordPress plugin versions before 1.8.1.759 expose a sensitive API credential on the post editor page to users with contributor-level access and above. This credential is used as the sole authorization mechanism for privileged REST API actions, enabling these users to escalate their privileges to publish arbitrary posts and perform other restricted operations.
