CVE-2024-35195 is a medium-severity vulnerability in psf requests, published on 20 May 2024. 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 Requests is a HTTP library. Prior to 2.32.0, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. This vulnerability is fixed in 2.32.0.

What it is: CVE-2024-35195 is a medium-severity vulnerability in psf requests, published on 20 May 2024. 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-2024-35195 in the wild and no public exploit code. Affected packages and fixed versions: - requests (PyPI): affected all versions; fixed in 2.32.0 - requests (PyPI): affected all versions; fixed in 2.32.0 - requests (PyPI): affected all versions; fixed in 2.32.0 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.
