KNIME Business Hub vulnerabilities

A wrong permission check in KNIME Business Hub before version 1.17.0 allowed an authenticated user to save jobs of other users as if they were saved by the job owner. The attacker must have permissions to access the jobs, but they were saved into the catalog service using the wrong owner permissions, potentially allowing saves into spaces where the attacker lacks write permissions.

An open redirect vulnerability existed in KNIME Business Hub prior to version 1.16.0. An unauthenticated remote attacker could craft a link to a legitimate KNIME Business Hub installation which, when opened by the user, redirects the user to a page of the attacker's choice. The problem has been fixed in KNIME Business Hub 1.16.0.

In KNIME Business Hub prior to 1.16.0, potentially sensitive information in jobs was visible to all team members. Starting with 1.16.0, only job metadata is shown to team members; only the job creator can see all information including in- and output data.

Missing HTTP headers (X-Frame-Options, Content-Security-Policy) in KNIME Business Hub before version 1.4.0 has left users vulnerable to clickjacking. This attack tricks users into clicking on actionable items, redirecting them to another server.
