AI Powered Q&A
Can you explain this vulnerability to me?
The Extensions for Leaflet Map plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in the 'elevation-track' shortcode in all versions up to and including 4.14.
This vulnerability exists because the plugin does not properly sanitize or escape user-supplied input attributes.
As a result, authenticated users with Contributor-level access or higher can inject malicious scripts into pages, which will execute whenever any user views those pages.
How can this vulnerability impact me? :
This vulnerability can allow attackers with Contributor-level access or above to inject arbitrary scripts into web pages.
These scripts can execute in the context of other users visiting the affected pages, potentially leading to theft of user credentials, session hijacking, or unauthorized actions performed on behalf of users.
Because the attack is stored, the malicious script persists on the site and affects all users who access the infected pages.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The vulnerability allows authenticated attackers with Contributor-level access to inject arbitrary web scripts via Stored Cross-Site Scripting (XSS). This can lead to unauthorized access or manipulation of user data when users access the injected pages.
Such unauthorized data access or manipulation could potentially violate data protection requirements under standards like GDPR and HIPAA, which mandate safeguarding personal and sensitive information against unauthorized disclosure or alteration.
However, specific impacts on compliance depend on the context of use, the nature of the data involved, and the presence of mitigating controls.
