CVE-2026-64836
ICEcoder versions through 8.1 contain a path traversal vulnerability in the file-control endpoint due to a logic error in the document-root confinement check.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.45%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
ICEcoder versions through 8.1 contain a path traversal vulnerability in the file-control endpoint due to a logic error in the document-root confinement check. The File::check() validation function compares realpath() to boolean true, which never succeeds, allowing authenticated attackers to submit traversal sequences or absolute paths in the file parameter to read, write, or delete files outside the configured document root.
