An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-8869 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- pip (PyPI): affected all versions; fixed in 25.3\n- pip (PyPI): affected all versions; fixed in 25.3\n- pip (PyPI): affected all versions; fixed in 25.3\n\nTask:\n1. 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.\n2. 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.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-8869/ (Markdown: https://insights.sbomify.com/CVE-2025-8869/index.md)","id":"CVE-2025-8869","markdown":"https://insights.sbomify.com/CVE-2025-8869/index.md","name":"CVE-2025-8869","record":{"aliases":["AZL-67788","BELL-CVE-2025-8869","CLEANSTART-2026-BZ71423","DEBIAN-CVE-2025-8869","ECHO-ffe1-1d3c-d9bc","GHSA-4xh5-x5gv-qwph","MINI-3r75-2w72-gmff","MINI-c3j7-c3p2-x3j8","MINI-f9cq-mwg9-63ww","MINI-hrv4-xxmc-6wfp","MINI-j6ww-7529-624g","MINI-j96j-jmq5-jp6m","MINI-jpcv-4gmj-6qj9","MINI-m28w-xvw5-pv5r","OESA-2025-2714","OESA-2025-2741","OESA-2025-2794","PYSEC-2026-1795","ROOT-APP-PYPI-CVE-2025-8869","ROOT-OS-DEBIAN-12-CVE-2025-8869","UBUNTU-CVE-2025-8869"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Python package installer","requires_auth":"none","summary":"Attackers can exploit pip's fallback tar extraction to write files outside the target directory via symbolic links, potentially leading to code execution.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"PSF","cpe":[],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[],"description":"When extracting a tar archive pip may not check symbolic links point into the extraction directory if the tarfile module doesn't implement PEP 706.\nNote that upgrading pip to a \"fixed\" version for this vulnerability doesn't fix all known vulnerabilities that are remediated by using a Python version that implements PEP 706.\n\nNote that this is a vulnerability in pip's fallback implementation of tar extraction for Python versions that don't implement PEP 706\nand therefore are not secure to all vulnerabilities in the Python 'tarfile' module.
