An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-19672 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- libpython (Bitnami): affected all versions; fixed in 3.10.22, 3.11.17, 3.12.15, 3.13.16, 3.14.8\n- python (Bitnami): affected all versions; fixed in 3.10.22, 3.11.17, 3.12.15, 3.13.16, 3.14.8\n- python-min (Bitnami): affected all versions; fixed in 3.10.22, 3.11.17, 3.12.15, 3.13.16, 3.14.8\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-2026-19672/ (Markdown: https://insights.sbomify.com/CVE-2026-19672/index.md)","id":"CVE-2026-19672","markdown":"https://insights.sbomify.com/CVE-2026-19672/index.md","name":"CVE-2026-19672","record":{"aliases":["ALPINE-CVE-2026-19672","AZL-110510","AZL-97038","BELL-CVE-2026-19672","BIT-libpython-2026-19672","BIT-python-2026-19672","BIT-python-min-2026-19672","DEBIAN-CVE-2026-19672","ECHO-85b0-6a57-a5e5","GHSA-prxg-vvhf-mgqq","MINI-4j2f-xmj7-f2pw","MINI-f3m3-jmm4-4v57","MINI-g45v-4wv4-fjpj","MINI-p789-r3r4-8gwh","MINI-r3v9-jr7p-qq28","PSF-2026-38","UBUNTU-CVE-2026-19672"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Python tarfile module","requires_auth":"none","summary":"Attackers can create empty directories outside the extraction destination via crafted tar archives, potentially disrupting filesystem structure.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"PSF","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:N/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"The tarfile module's tar and data\n extraction filters created directories outside the destination for \nmembers whose name leaves the destination and returns to it, such as ../evil/../dest/sub/file.
