CVE-2023-5752 is a medium-severity command injection vulnerability in pip, published on 24 Oct 2023. It can only be exploited from the same machine or local network, with no action from the victim. ### Official description 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. Weakness: CWE-77 (Improper Neutralization of Special Elements used in a Command) ## Which versions are affected by CVE-2023-5752? 3 open source packages ship an affected version, including pip.

What it is: CVE-2023-5752 is a medium-severity command injection vulnerability in pip, published on 24 Oct 2023. It can only be exploited from the same machine or local network, with no action from the victim. Exploitation: There is no known exploitation of CVE-2023-5752 in the wild and no public exploit code. Affected packages and fixed versions: - pip (PyPI): affected all versions; fixed in 23.3 - pip (PyPI): affected all versions; fixed in 23.3 - pip (PyPI): affected all versions; fixed in 23.3 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.
