Summary
Craft is a CMS for creating custom digital experiences on the web and beyond. Bypassing the validatePath function can lead to potential remote code execution. This vulnerability can lead to malicious control of vulnerable systems and data exfiltrations. Although the vulnerability is exploitable only in the authenticated users, configuration with ALLOW_ADMIN_CHANGES=true, there is still a potential security threat (Remote Code Execution). This issue has been patched in version 4.4.15 and version 3.8.15.
