The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation). The technical assessment indicates that the vulnerability allows for cross-site scripting attacks through the plugin's shortcode functionality (NVD).

The vulnerability allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages. These malicious scripts will execute whenever a user accesses an affected page, potentially compromising the security of site visitors (NVD).
