CVE-2026-8643 is a medium-severity path traversal vulnerability in Python Packaging Authority pip, published on 1 Jun 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link. ### Official description pip would treat console_scripts and gui_scripts as paths instead of file names without sanitizing the resolved absolute path to the installation directory, leading to entry points being installed outside the installation directory. Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory) ## Which versions are affected by CVE-2026-8643? 3 open source packages ship an affected version, including pip.

What it is: CVE-2026-8643 is a medium-severity path traversal vulnerability in Python Packaging Authority pip, published on 1 Jun 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link. Exploitation: There is no known exploitation of CVE-2026-8643 in the wild and no public exploit code. Affected packages and fixed versions: - pip (PyPI): affected all versions; fixed in 26.1.2 - pip (PyPI): affected all versions; fixed in 26.1.2 - pip (PyPI): affected all versions; fixed in 26.1.2 Task: 1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
