CVE-2026-73329

CamaleonCMS contains a stored cross-site scripting vulnerability that allows authenticated low-privileged users to execute arbitrary JavaScript in an administrator's browser by injecting unsanitized HTML payloads into the post title parameter during draft creation. Attackers can submit a malicious HTML payload as a draft title through the drafts creation endpoint, which is persisted to the database without escaping and later rendered as raw HTML in the admin drafts listing, enabling administrator session compromise, cookie theft, and forged authenticated requests.
