Vulnerability Overview
The Social Author Bio plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.4. This is due to missing or incorrect nonce validation on an unknown function. This makes it possible for unauthenticated attackers to inject malicious JavaScript granted they can trick a site administrator into performing an action such as clicking on a link. The impact of this vulnerability is unknown.
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.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in Social Author Bio <= 2.4 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. No fixed build of this plugin is recorded for Social Author Bio yet, so installs running <= 2.4 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
The attempt arrives as an ordinary request to Social Author Bio: WordSec's web application firewall inspects request payloads before WordPress loads them. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
