# CVE-2026-6357: pip Vulnerable to Inclusion of Functionality from Untrusted Control Sphere

## TL;DR
pip Vulnerable to Inclusion of Functionality from Untrusted Control Sphere

## Key Points
- cve / CVE-2026-6357 / PYSEC-2026-2876 / severity:CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:A/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N / pip / PyPI

## Details
**Severity:** CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:A/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N
**Advisory:** PYSEC-2026-2876 (CVE-2026-6357)

**Affected (your watchlist):**
- `PyPI:pip` 24.0 → fixed in 26.1 [docker/docker-portal+docker/local+docker/mac]
- `PyPI:pip` 25.0.1 → fixed in 26.1 [docker/docker-graphrag+docker/docker-llmwiki+docker/docker-portal+docker/docker-strands+docker/local+docker/mac]
- `PyPI:pip` 25.1.1 → fixed in 26.1 [docker/docker-mcp]
- `PyPI:pip` 26.0.1 → fixed in 26.1 [docker/docker-llmwiki]

**Details:**
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.
