    CVE-2023-5752

    Published: 24 Oct 2023Last Modified: 28 Oct 2026

    Summary: Mercurial configuration injectable in repo revision when installing via pip

    Details: 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.
