Deeper analysis
The Professional Social Sharing Buttons, Icons & Related Posts WordPress plugin before version 9.7.6 contains an authorization flaw (CWE-863) in an AJAX handler. The affected component fails to enforce access controls on an action that returns environment details including the list of active plugins along with PHP, cURL, and WordPress version strings. The issue is rated CVSS 5.3 and was disclosed on 25 July 2022.
Unauthenticated visitors (prior to 9.7.5) or any user with the Author role (in 9.7.5) can invoke the handler directly over the network. Successful exploitation yields reconnaissance data that can be used to identify additional vulnerabilities or to tailor subsequent attacks against the site.
The referenced WPScan advisory recommends updating the plugin to 9.7.6 or later, which restores the missing authorization check. No evidence of in-the-wild exploitation is provided in the supplied data, and the EPSS score has remained flat at 0.4983.
