What is CVE-2026-102133?
CVE-2026-102133 is a medium-severity command injection vulnerability in Accellion Kiteworks, published on 30 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
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.
