CVE-2018-20225 is a dependency-confusion issue in pip's package-index resolution behavior. When pip is configured with --extra-index-url, it considers package versions across the configured indexes and selects the highest version. If an organization intends to retrieve a private package but that package name is not already present on the public index, an attacker can publish a package with the same name and a higher version to the public index, causing pip to select the attacker-controlled package. The behavior has also been characterized as intended pip functionality, making secure index configuration central to preventing exposure.

3 sources tracked across advisories, community write-ups, and news. New activity surfaces here as Mallory finds it.
A pip dependency-confusion issue affecting use of the --extra-index-url option. pip can select a higher-versioned package from the public index instead of the intended private package when that package name is absent from the public index, allowing an attacker to publish an arbitrary higher-versioned package.
A pip package installation behavior issue (dependency confusion) where using --extra-index-url (or equivalent configuration) can cause pip to select and install an attacker-controlled package from a public index (e.g., PyPI) over the intended private package, if the attacker publishes the same package name with a higher version.
