PatchTheCVECVE-2026-102101: Kiteworks Core before version 9.5.0 is vulnerable to Deserialization of Untrusted Data
CVE-2026-102101 is a high-severity flaw (CVSS 8.1) affecting kiteworks. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
Kiteworks Core before version 9.5.0 is vulnerable to Deserialization of Untrusted Data. A deserialization weakness in Kiteworks Core could, under certain conditions, allow crafted data to be deserialized unsafely, potentially resulting in remote code execution on the appliance. Exploitation depends on an attacker first being able to influence the affected data, so this issue is not exploitable on its own.
Why this priority
- High severity
A fixed release or distro patch exists.
