Deeper analysis
The Restrict Content plugin for WordPress from StellarWP, in versions up to and including 3.2.7, is affected by CVE-2023-47668, an Exposure of Sensitive Information to an Unauthorized Actor vulnerability (CWE-200) with a CVSS 3.1 score of 5.3. The issue stems from improper handling that exposes sensitive data, specifically noted in vulnerability records as occurring via log files.
Unauthenticated remote attackers can exploit the flaw over the network with low complexity and no user interaction required, resulting in limited disclosure of sensitive information while leaving integrity and availability unaffected. This allows any network-accessible actor to retrieve data that should remain restricted without needing credentials or special privileges.
Advisories published on Patchstack identify the root cause as sensitive data exposure through log files in the Restrict Content plugin at version 3.2.7 and provide the associated technical details for the CVE. The EPSS score has remained flat at 0.0547 with no material increase observed since disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Automated marking applies security attributes to system outputs, making it harder for attackers to exploit unmarked sensitive information leading to unauthorized exposure.
Proper attribute retention and permitted-value enforcement limits unauthorized actors from accessing sensitive information lacking correct labels.
Prevents unauthorized exposure of sensitive information by prohibiting untrusted external systems from processing or storing it.
By enforcing authorization matching prior to sharing, the control reduces the risk of exposing sensitive information to unauthorized actors.
Review and removal of nonpublic information from publicly accessible systems directly prevents exposure of sensitive data to unauthorized actors.
Data mining protection mechanisms detect and block unauthorized bulk extraction of sensitive data, directly mitigating exposure to unauthorized actors.
Literacy training teaches users to recognize and avoid actions that result in unauthorized exposure of sensitive information.
Retaining and monitoring training records confirms personnel have completed privacy and security awareness training on handling sensitive data, reducing the chance of unauthorized exposure due to lack of knowledge.
