CVE-2026-64836— ICEcoder through 8.1 Path Traversal via Ineffective File::check() Confinement

Quick assessment

Affected
ICEcoder ICEcoder
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

ICEcoder 8.1 及更早版本中存在路径遍历漏洞，其成因在于文件控制端点中的文档根目录限制检查存在逻辑错误。 校验函数将 的结果与布尔值 进行比较，该比较永远无法成功。这使得经过身份验证的攻击者可以在文件参数中提交遍历序列或绝对路径，从而能够读取、写入或删除配置文档根目录之外的文件。

Vulnerability Title
ICEcoder through 8.1 Path Traversal via Ineffective File::check() Confinement
Source: CVE Program / CVE List V5
Vulnerability 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.
