Can you explain this vulnerability to me?
The Credits Shortcode plugin for WordPress has a vulnerability known as Stored Cross-Site Scripting (XSS) in its 'link' attribute of the 'credits' shortcode. This occurs 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 malicious scripts into pages. These scripts will execute whenever any user accesses the affected page.
How can this vulnerability impact me? :
This vulnerability allows attackers with contributor-level access to inject arbitrary web scripts into pages, which can then execute in the browsers of users who visit those pages.
The impact includes potential compromise of user data confidentiality and integrity, as the injected scripts can steal information or perform actions on behalf of users without their consent.
According to the CVSS v3.1 score of 6.4, the vulnerability has a medium severity with low attack complexity, requiring privileges but no user interaction, and can lead to partial confidentiality and integrity loss.
