    Title
    Kiteworks Email Protection Gateway Improper Access Control
    Summary
    Kiteworks Email Protection Gateway did not sufficiently restrict which account a certificate could be assigned to. This could allow an attacker to associate a certificate with another user's account, affecting the confidentiality and integrity of that account's encrypted mail and, where certificate-based login is enabled, potentially permitting unauthorized access to the account.

    Title
    Kiteworks Core Administrative Account Takeover through Stored Cross-site Scripting (XSS)
    Summary
    A stored cross-site scripting (XSS) weakness in Kiteworks Core could allow an unauthenticated attacker to store crafted content that later executes arbitrary JavaScript in the authenticated session of an administrator who views the affected page. This could have permitted the attacker to gain full administrative control, including the creation of a new administrative account.

    CVE-2026-102143 (GCVE-0-2026-102143)

    Vulnerability from nvd – Published: 2026-09-30 20:10 – Updated: 2026-09-30 20:10

    Title
    Kiteworks Email Protection Gateway Unrestricted Upload of File with Dangerous Type
    Summary
    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.

    Title
    Kiteworks Core Privilege Escalation through External Control of File Name or Path
    Summary
    Two Kiteworks Core cluster-management operations did not validate file paths supplied to them, so an attacker holding root on one node of a cluster could write files as root onto another node and cause them to be executed there. Exploitation requires backend root access on a cluster node and a pending software patch present on the target node.

    Kiteworks Core Insufficient Verification of Data Authenticity
    Summary
    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.

    Title
    Kiteworks Core Command Execution through Configuration Injection
    Summary
    In multi-node deployments, an attacker who had already obtained code execution on one appliance node could submit a value through an internal cluster interface that was written into monitoring configuration on another node without sufficient validation, potentially allowing OS commands to be executed there. Execution was limited to an unprivileged service account on that node.

    Title
    Kiteworks Email Protection Gateway Deserialization of Untrusted Data
    Summary
    On a Kiteworks Email Protection Gateway cluster with database replication enabled, a party trusted by the cluster could submit a crafted serialized object that was deserialized without sufficient validation, potentially allowing code execution as the gateway service account. Replication is disabled by default, and exploitation requires control of a trusted cluster peer or administrative access to the appliance.

    Title
    Kiteworks Core Arbitrary File Write through Command Injection
    Summary
    An optional, separately licensed repository-connector feature in Kiteworks Core did not neutralize special characters in a user-supplied path before passing it to an external command. An authenticated system administrator could inject additional commands and write arbitrary content to files owned by the service account running the connector, enabling code execution in that account's context; exploitation additionally requires network egress from the appliance to a system under the attacker's control.

    Title
    Kiteworks Core Privilege Escalation through Improper Access Control
    Summary
    An administrative import function in Kiteworks Core did not verify that the requesting administrator was entitled to create the privileged integration credential being imported. A delegated administrator holding a single narrowly scoped administrative permission could therefore obtain full system administrator privileges, without any action by an existing system administrator.

    Kiteworks Email Protection Gateway rejected certain configuration settings, but its validation did not recognize every form in which they could be supplied. An authenticated administrator could potentially use an unrecognized form to have a file of their choosing written to the gateway and executed, resulting in code execution as the gateway service account.

    Kiteworks Core Incorrect Privilege Assignment
    Summary
    A user-provisioning interface in Kiteworks Core did not verify that the requesting administrator was entitled to grant the role being assigned. An administrator whose delegated permissions covered role changes alone could therefore raise an account to full system-administrator privileges.

    Title
    Kiteworks Email Protection Gateway Improper Authentication
    Summary
    An identity-verification weakness in Kiteworks Email Protection Gateway allowed the gateway to act on the Kiteworks platform on behalf of a user it had not authenticated, and to provision a platform account for an identity it did not already know. A remote, unauthenticated sender could potentially exploit this to obtain control of a platform account.

    Title
    Kiteworks Email Protection Gateway Improper Restriction of XML External Entity Reference
    Summary
    An XML parser used by Kiteworks Email Protection Gateway did not restrict external entity references. Where an optional, non-default message-processing feature is enabled, a remote and unauthenticated sender could potentially use a crafted message to read files accessible to the gateway service account, including cryptographic key material and credentials, and have them sent to a destination they control.

    Title
    Kiteworks Core Stored Cross-site Scripting (XSS)
    Summary
    A stored cross-site scripting (XSS) weakness in Kiteworks Core could allow an administrator holding only a single, narrowly scoped delegated permission to store crafted content that later executes arbitrary JavaScript in the authenticated session of a System Administrator who views the affected page. This could have permitted the lower-privileged administrator to escalate to full administrative control of the tenant, including the creation of a new administrative account.

    Title
    Kiteworks Core Sandbox Escape
    Summary
    The sandbox that isolates document conversion on a Kiteworks appliance did not fully confine the code running inside it. Code already executing within that sandbox could potentially escape its confinement and act with the privileges of the service account that runs the application, which could allow an attacker in that position to read or modify application data and configuration, or to disrupt the service on the affected appliance.

    Title
    Kiteworks Core Path Traversal
    Summary
    A Kiteworks appliance setup interface did not confine a user-supplied file path to its intended directory, which could allow an unauthenticated attacker to write a file to any location writable by the affected service account, potentially compromising the integrity of the appliance or rendering it unavailable until an operator intervenes. Exploitation requires network access to the affected interface, which is not reachable on a fully configured appliance in its default configuration; reaching it depends on either the transient window while an appliance is first being provisioned or a non-default appliance configuration.

    Title
    Kiteworks Secure Data Forms Exposure of Sensitive Information to an Unauthorized Actor
    Summary
    A form-rendering interface in the Advanced Forms component is reachable without authentication so that published forms can be displayed to anonymous visitors, but it returned more data than the form itself required. Anyone who knew the web address of a published form could potentially retrieve the form owner's Kiteworks account profile, including personal details, along with parts of the deployment's configuration settings; no passwords, authentication tokens, or multi-factor secrets were exposed.

    Title
    Kiteworks Core OS Command Injection
    Summary
    A privilege escalation vulnerability in Kiteworks could have allowed an attacker who had already obtained code execution on one node of a clustered Kiteworks deployment to run operating system commands with elevated privileges on another node of the same cluster. Insufficient input validation in an internal cluster management function let attacker-supplied values reach a privileged execution context; exploitation requires existing access to a node in the cluster, and the affected function is not reachable from outside the cluster.
