This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires that a published page or post on the target site contains the [meta_data_filter_results] shortcode, which is the primary output feature of the plugin.\n\n## Affected\n\n- `mdtf_meta_data_and_taxonomies_filter <= 1.4.1`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":40,"depthScoreParts":{"impact":39.6,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
