CVE-2026-102140
Kiteworks Core Insufficient Verification of Data Authenticity
Description
An authenticated administrator could initiate an administrative import using a file whose contents were not fully verified, because the import validated only the file's header rather than the complete file. This could allow unverified or forged content to be accepted and processed, affecting the integrity of the imported data.
