Vulnerability Overview
The Professional Social Sharing Buttons, Icons & Related Posts WordPress plugin before 9.7.6 does not have proper authorisation check in one of the AJAX action, available to unauthenticated (in v < 9.7.5) and author+ (in v9.7.5) users, allowing them to call it and retrieve various information such as the list of active plugins, various version like PHP, cURL, WP etc.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.
CWE-863: Incorrect Authorization
Reaching this weakness in Professional Social Sharing Buttons, Icons & Related Posts <= 9.7.5 takes a caller who can reach the endpoint. Incorrect authorization means a permission check exists but evaluates the wrong thing, so it passes for callers it was meant to stop.
The action runs for users the code intended to exclude, with the same effect as having no check at all. For Professional Social Sharing Buttons, Icons & Related Posts the fix is 9.7.6: builds <= 9.7.5 are affected, anything from 9.7.6 onward is not.
Remediation
Update to version 9.7.6, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Professional Social Sharing Buttons, Icons & Related Posts 9.7.6 closes this, and updating the plugin is the step that ends it.
