A flaw was found in pip. Prior to version 26.1, pip's self-update check functionality would execute after installing wheel packages. This process involved importing newly installed Python modules. A malicious actor could craft a specially designed wheel package that, when installed, could lead to the execution of arbitrary code or information disclosure due to the premature import of its modules during the self-update check.
