CVE-2026-6357 (GCVE-0-2026-6357)

Vulnerability from nvd – Published: 2026-04-27 14:19 – Updated: 2026-04-27 22:17
VLAI?
Title
pip self-update functionality can import newly installed modules after wheel installation
Summary
pip prior to version 26.1 would run self-update check functionality after installing wheel files which required importing well-known Python modules names. These module imports were intentionally deferred to increase startup time of the pip CLI. The patch changes self-update functionality to run before wheels are installed to prevent newly-installed modules from being imported shortly after the installation of a wheel package. Users should still review package contents prior to installation.

CVE-2023-5752 (GCVE-0-2023-5752)

Vulnerability from nvd – Published: 2023-10-24 20:56 – Updated: 2025-11-03 17:31

Title
Mercurial configuration injectable in repo revision when installing via pip
Summary
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.

CVE-2026-6357 (GCVE-0-2026-6357)

Vulnerability from cvelistv5 – Published: 2026-04-27 14:19 – Updated: 2026-04-27 22:17
VLAI?
Title
pip self-update functionality can import newly installed modules after wheel installation
Summary
pip prior to version 26.1 would run self-update check functionality after installing wheel files which required importing well-known Python modules names. These module imports were intentionally deferred to increase startup time of the pip CLI. The patch changes self-update functionality to run before wheels are installed to prevent newly-installed modules from being imported shortly after the installation of a wheel package. Users should still review package contents prior to installation.

CVE-2023-5752 (GCVE-0-2023-5752)

Vulnerability from cvelistv5 – Published: 2023-10-24 20:56 – Updated: 2025-11-03 17:31

Title
Mercurial configuration injectable in repo revision when installing via pip
Summary
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.
