IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to execute arbitrary code and access sensitive information from other tenants due to insufficient input validation. Uploaded custom module content is not sufficiently validated before it is processed, which could allow code to run with access beyond the user's own tenant.
