EPSS Percentile

CamaleonCMS contains a missing authorization vulnerability that allows any authenticated low-privileged user to access and modify plugin settings by reaching four unprotected plugin-administration endpoints without administrator-level authorization. Attackers can manipulate plugin configuration parameters at runtime across the attack, front_cache, cama_meta_tag, and cama_contact_form plugins to alter cached page behavior, modify public meta-tag output, or reconfigure contact forms, enabling account takeover when chained with stored cross-site scripting through the contact form's before_html field.
