CVE-2026-73326 is a high-severity missing authorization vulnerability in owen2345 CamaleonCMS, published on 12 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

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.
