What it is

When installing a package from a Mercurial VCS URL (ie "pip install

hg+...") with pip prior to v23.3, the specified Mercurial revision could

be used to inject arbitrary configuration options to the "hg clone"

call (ie "--config"). Controlling the Mercurial configuration can modify

how and which repository is installed. This vulnerability does not

affect users who aren't installing from Mercurial.
