The CVSS score of 6.5 indicates a moderate severity. EPSS data is not available, and the vulnerability is not listed in the CISA KEV catalog. Exploitation requires a valid authenticated account with Subscriber or higher privileges, a level of access that is commonly assigned to many users of WordPress sites.
