Can you explain this vulnerability to me?
This vulnerability is a Stored Cross-Site Scripting (XSS) issue in the Passster – Password Protect Pages and Content WordPress plugin. It occurs via the plugin's 'content_protector' shortcode in versions up to 4.2.24. Authenticated attackers with Contributor-level access or higher can inject malicious scripts into pages, which then execute whenever any user accesses those pages. The vulnerability was partially fixed in version 4.2.21 but remains exploitable in later versions up to 4.2.24.
How can this vulnerability impact me? :
This vulnerability allows attackers with Contributor-level access to inject arbitrary scripts into protected pages. These scripts execute in the context of users visiting those pages, potentially leading to theft of user data, session hijacking, or other malicious actions. It compromises the integrity and security of the website and its users.
What immediate steps should I take to mitigate this vulnerability?
Update the Passster – Password Protect Pages and Content plugin to a version later than 4.2.24, as the vulnerability is present in all versions up to and including 4.2.24. The vulnerability was partially patched in version 4.2.21, so ensure you are running the latest patched version to mitigate the risk.
