The Featured Image with URL WordPress plugin before 1.0.6 does not sanitise and escape a stored image attribute value before outputting it, which could allow users with a role as low as Contributor to perform Stored Cross-Site Scripting attacks that execute in the browser of any user viewing the affected post, including higher-privileged users such as Editors and Administrators.
AI Analysis
Technical Summary
The Featured Image with URL WordPress plugin versions prior to 1.0.6 do not properly sanitize and escape a stored image attribute value before rendering it in posts. This flaw enables users with Contributor-level permissions to perform stored Cross-Site Scripting (CWE-79) attacks. The malicious payload executes in the browsers of users who view the affected posts, potentially impacting users with elevated privileges.
Potential Impact
Users with Contributor roles can inject persistent malicious scripts that execute in the browsers of any user viewing the affected post, including Editors and Administrators. This could lead to session hijacking, privilege escalation, or other attacks depending on the malicious payload, compromising site security and user data.
Mitigation Recommendations
Upgrade the Featured Image with URL plugin to version 1.0.6 or later where this vulnerability is fixed. No other mitigation is indicated by the vendor advisory. Until patched, restrict Contributor role capabilities or avoid using the plugin.
