CVE-2026-64836
ICEcoder through 8.1 Path Traversal via Ineffective File::check() Confinement
CVSS Score
8.8
EPSS Score
0.0%
EPSS Percentile
0th
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.
