CVE-2024-12263 is a vulnerability classified under CWE-862 (Missing Authorization) found in the Child Theme Creator by Orbisius WordPress plugin, specifically within the Cloud Library Addon component used by the plugin. The issue stems from the absence of capability checks in the cloud_delete() and cloud_update() functions, which handle deletion and updating of cloud snippets. This flaw allows any authenticated user with at least Subscriber-level access to perform unauthorized modifications or deletions of cloud snippets, potentially leading to data integrity issues. The vulnerability affects all versions up to and including 1.5.5. It is important to note that the vulnerability resides in the Cloud Library Addon, not the main Child Theme Creator plugin, and the addon has been removed entirely to mitigate the issue. The CVSS v3.1 base score is 4.3, reflecting a medium severity level due to the ease of exploitation by low-privilege authenticated users and the impact limited to integrity without affecting confidentiality or availability. No user interaction is required, and no known exploits have been reported in the wild. The vulnerability was publicly disclosed on December 12, 2024, and assigned by Wordfence. The lack of authorization checks in these functions represents a common security oversight that can be exploited to manipulate plugin data in WordPress environments.

The primary impact of CVE-2024-12263 is unauthorized modification and deletion of cloud snippets within the affected plugin component, which compromises data integrity. While the vulnerability does not expose sensitive information or disrupt service availability, unauthorized changes could lead to corrupted or lost configuration data, potentially affecting website functionality or appearance. Since exploitation requires only Subscriber-level access, attackers who gain low-privilege accounts—through phishing, credential stuffing, or other means—can leverage this flaw to escalate their influence within the WordPress site. This can undermine trust in the website's content and may facilitate further attacks if the snippets control critical theme or plugin behavior. Organizations relying on this plugin for theme management risk operational disruptions and potential reputational damage if attackers manipulate site content. However, the removal of the vulnerable Cloud Library Addon reduces the attack surface, limiting widespread exploitation. The medium severity rating reflects the moderate risk posed, especially for sites with multiple low-privilege users or weak authentication controls.

To mitigate CVE-2024-12263, organizations should first verify whether the Cloud Library Addon is installed and active within their Child Theme Creator by Orbisius plugin environment. Since the addon has been removed entirely due to this vulnerability, uninstalling or disabling it is the most effective immediate step. If the addon is still present, update to the latest plugin version that excludes the vulnerable component. Additionally, enforce strict user role management by limiting Subscriber-level access and regularly auditing user accounts to prevent unauthorized access. Implement strong authentication mechanisms such as multi-factor authentication (MFA) to reduce the risk of account compromise. Monitor WordPress logs for unusual activity related to cloud snippet modifications. For organizations that require cloud snippet functionality, consider alternative plugins with robust authorization checks. Finally, maintain regular backups of WordPress site data to enable recovery in case of unauthorized modifications.
