AI Powered Q&A
Can you explain this vulnerability to me?
The Posts map plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) through the 'name' shortcode attribute in all versions up to and including 0.1.3.
This vulnerability exists because the plugin does not properly sanitize or escape user-supplied input in this attribute.
As a result, authenticated users with contributor-level access or higher can inject arbitrary web scripts into pages.
These scripts will execute whenever any user accesses the injected page, potentially compromising the site or user data.
How can this vulnerability impact me? :
This vulnerability allows attackers with contributor-level access or above to inject malicious scripts into WordPress pages.
When other users visit these pages, the injected scripts execute in their browsers, which can lead to theft of user credentials, session hijacking, or unauthorized actions performed on behalf of users.
Because the attack is stored, the malicious code persists on the site until removed, increasing the risk and potential damage.
The CVSS score of 6.4 indicates a medium severity with network attack vector, low attack complexity, and no user interaction required.
What immediate steps should I take to mitigate this vulnerability?
The Posts map plugin for WordPress has been closed as of April 15, 2026, and is not available for download pending a full review.
As an immediate mitigation step, you should uninstall or deactivate the Posts map plugin to prevent exploitation of the stored cross-site scripting vulnerability.
Additionally, restrict contributor-level access and above until a patched version is released.
