The Kutethemes Biolife WordPress theme contains a missing authorization flaw that allows unauthenticated users to submit and execute arbitrary shortcodes. This misconfiguration in access controls lets the theme process any shortcode supplied, potentially injecting malicious code. The result can be content tampering, site defacement, or further compromise of the WordPress installation.

WordPress sites using the Kutethemes Biolife theme version 3.2.3 or earlier are affected. The vulnerability applies to all releases from an undocumented initial release through version 3.2.3; newer releases beyond 3.2.3 are not affected. No other vendors or products are listed in the advisory.

The CVSS score of 5.3 indicates moderate severity, and the EPSS score of less than 1% suggests a low likelihood of exploitation in the wild. The vulnerability is not listed in CISA's Known Exploited Vulnerabilities catalog. Based on the description, it is inferred that the attack vector is through a public interface where an attacker submits a malicious shortcode, exploiting the theme's lack of access control to run code without authentication.
