CVE-2023-5070
Published: 20 October 2023
Summary
CVE-2023-5070 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor (CWE-200) vulnerability in Ultimatelysocial Social Media Share Buttons \& Social Sharing Icons. Its CVSS base score is 6.5 (Medium).
Operationally, ranked in the top 5.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The Social Media Share Buttons & Social Sharing Icons plugin for WordPress is affected by a sensitive information exposure vulnerability in versions up to and including 2.8.5. The flaw resides in the sfsi_save_export function and is tracked as CWE-200, allowing exposure of plugin settings that contain social media authentication tokens, secrets, and app passwords. It carries a CVSS 3.1 score of 6.5 reflecting network attack vector, low complexity, and low privileges required.
Subscribers on an affected site can invoke the function to export the stored credentials, achieving disclosure of high-value authentication material without any user interaction or change in scope. This enables an attacker with subscriber-level access to obtain tokens and passwords that could be reused against linked social media accounts or applications.
References from Wordfence and the WordPress plugin repository document a fix released in version 2.8.6, with the changeset updating the sfsi_buttons_controller.php file to address the export function behavior. Site administrators are advised to update the plugin to the patched release to prevent unauthorized export of sensitive settings.
The EPSS score reached a peak of 0.1573 with a current value of 0.1340, indicating modest post-disclosure interest but no evidence of widespread exploitation in the provided data.

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.
