# CVE-2022-47950: OpenStack Swift XML external entities (XXE) Injection > Authenticated users can read arbitrary files from the host server via crafted XML requests in the S3 API, exposing sensitive data. - **Severity:** Medium 6.5 (`CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N`) - **Exploited in the wild:** Not known - **Login needed:** Any signed-in user - **Attackable:** Over the internet - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 18 Jan 2023 - **Updated:** 4 Apr 2025 - **Also known as:** DEBIAN-CVE-2022-47950, DLA-3281-1, DSA-5327-1, GHSA-274c-rx2j-2v3x, PYSEC-2026-927, RHSA-2023:1013, RHSA-2023:1277, SUSE-SU-2023:0323-1, UBUNTU-CVE-2022-47950, USN-5852-1 ## What is CVE-2022-47950? CVE-2022-47950 is a medium-severity path traversal vulnerability in Debian Debian Linux, published on 18 Jan 2023. Any signed-in user can exploit it over the network, with no action from the victim. ### Official description An issue was discovered in OpenStack Swift before 2.28.1, 2.29.x before 2.29.2, and 2.30.0. By supplying crafted XML files, an authenticated user may coerce the S3 API into returning arbitrary file contents from the host server, resulting in unauthorized read access to potentially sensitive data. This impacts both s3api deployments (Rocky or later), and swift3 deployments (Queens and earlier, no longer actively developed).

What it is: CVE-2022-47950 is a medium-severity path traversal vulnerability in Debian Debian Linux, published on 18 Jan 2023. Any signed-in user can exploit it over the network, with no action from the victim. Exploitation: There is no known exploitation of CVE-2022-47950 in the wild and no public exploit code. Affected packages and fixed versions: - swift (PyPI): affected all versions; fixed in 2.28.1, 2.29.2, 2.30.1 - swift (PyPI): affected all versions; fixed in 2.28.1 - swift (PyPI): affected all versions; fixed in 2.28.1 - swift (PyPI): affected from 2.29.0; fixed in 2.29.2 - swift (PyPI): affected from 2.29.0; fixed in 2.29.2 - swift (PyPI): affected from 2.30.0; fixed in 2.30.1 - swift (PyPI): affected from 2.30.0; fixed in 2.30.1 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.
