CVE-2026-67616 in Camaleon CMS
Summary
by MITRE • 08/04/2026
Camaleon CMS through 2.9.2, fixed in commit 88ab703, contains a missing authorization vulnerability on the drafts endpoint that allows any authenticated low-privileged user to create draft posts by bypassing role and permission checks. Attackers can send requests to the drafts endpoint using only session authentication to create unauthorized drafts that appear in the administrative drafts queue.

This vulnerability exists within Camaleon CMS version 2.9.2 and earlier, representing a critical authorization flaw that undermines the platform's access control mechanisms. The issue stems from insufficient validation of user permissions when processing requests to the drafts endpoint, allowing any authenticated user regardless of their role or privileges to create draft posts without proper authorization. This represents a direct violation of the principle of least privilege and demonstrates a fundamental failure in the application's permission architecture.
The technical implementation flaw occurs at the endpoint level where the system fails to verify whether the requesting user possesses the necessary administrative rights to create drafts. Authentication tokens are accepted without adequate authorization checks, enabling low-privileged users to exploit this gap through straightforward http requests that target the drafts functionality. The vulnerability is particularly concerning because it operates entirely within the session-based authentication framework, making it accessible to any user who has successfully logged into the system.
Operationally, this vulnerability creates a significant risk for content management systems where draft posts often contain sensitive information or unreleased content. Attackers can leverage this flaw to submit unauthorized drafts that remain visible in the administrative queue, potentially leading to data exposure, content manipulation, or even social engineering opportunities. The impact extends beyond simple privilege escalation as it allows malicious actors to pollute the content management workflow with unauthorized submissions that may go unnoticed until discovered during routine administrative review.
The vulnerability maps directly to CWE-285 which addresses improper authorization within software applications, and aligns with ATT&CK technique T1078.004 related to valid accounts for gaining access to systems. This represents a classic case of insufficient access control enforcement where the application assumes that authenticated users are authorized to perform all administrative functions. The fix implemented in commit 88ab703 addresses this by adding proper authorization checks that validate user roles before permitting draft creation operations, ensuring only users with appropriate permissions can access this functionality.
Organizations utilizing Camaleon CMS should immediately implement the patched version and conduct thorough security assessments of their content management workflows. Administrators should review existing draft queues for unauthorized submissions and consider implementing additional monitoring mechanisms to detect anomalous content creation patterns. The vulnerability highlights the critical importance of proper input validation and authorization checking in web applications, particularly those handling sensitive content management operations where unauthorized access can have far-reaching consequences for organizational security posture and data integrity.
