PatchTheCVECVE-2026-102143: An unauthenticated attacker could cause a file with attacker-controlled content to be written to the appliance
CVE-2026-102143 is a high-severity flaw (CVSS 7.5) affecting kiteworks. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
An unauthenticated attacker could cause a file with attacker-controlled content to be written to the appliance filesystem through an administrative upload handler that did not properly authenticate the request. This did not by itself result in code execution, which would require a separate vulnerability to place the file in an executable location.
