CVE-2026-73332: CamaleonCMS cama_contact_form Plugin Stored XSS via before_html Field

CamaleonCMS contains a stored cross-site scripting vulnerability in the camacontactform plugin that allows low-privileged authenticated attackers to inject arbitrary HTML by submitting unsanitized content to the beforehtml field through the contact form edit endpoint, which lacks proper authorization controls. Attackers can persist malicious script payloads into the database that execute in victims' browsers when the contact form loads, enabling cookie theft, forged authenticated requests against the admin interface, and session takeover of viewing users.
