What is CVE-2026-64836?

ICEcoder versions up to 8.1 are affected by a path traversal vulnerability within the file-control endpoint due to an oversight in the document-root confinement mechanism. The validation function File::check() incorrectly employs a comparison between realpath() and a boolean true, which perpetually fails. This flaw allows authenticated attackers to leverage traversal sequences or absolute paths in the file parameter. As a result, these malicious users can access, alter, or eliminate files outside the defined document root, posing significant security risks.

Affected Version(s)

ICEcoder 8.0 <= 8.1
