It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-82049 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\n- python (Bitnami): affected all versions; fixed in 3.10.22, 3.11.17, 3.12.15, 3.13.16\n- python-min (Bitnami): affected all versions; fixed in 3.10.22, 3.11.17, 3.12.15, 3.13.16\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-2026-82049/ (Markdown: https://insights.sbomify.com/CVE-2026-82049/index.md)","id":"CVE-2026-82049","markdown":"https://insights.sbomify.com/CVE-2026-82049/index.md","name":"CVE-2026-82049","record":{"aliases":["ALPINE-CVE-2026-82049","AZL-101784","AZL-101832","BELL-CVE-2026-82049","BIT-libpython-2026-82049","BIT-python-2026-82049","BIT-python-min-2026-82049","CLSA-2026-1789662396","CLSA-2026-1789719542","CLSA-2026-1789719876","CLSA-2026-1789736914","CLSA-2026-1789749056","CLSA-2026-1792411096","DEBIAN-CVE-2026-82049","ECHO-ce85-5a2e-16be","GHSA-ghff-gcpf-9r9p","MINI-gp7v-r49g-fjvx","MINI-hrc8-58gw-42wj","MINI-m4vj-4h7j-c7w5","MINI-pmjg-g8q5-5c97","MINI-x6vr-cm4w-9x57","PSF-0000-CVE-2026-82049","PSF-2026-41","ROOT-OS-DEBIAN-13-CVE-2026-82049","SUSE-SU-2026:4738-1","SUSE-SU-2026:4904-1","UBUNTU-CVE-2026-82049"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Python tarfile module","requires_auth":"none","summary":"Attackers can craft tar archives to modify permissions or disclose contents of files outside the extraction directory via hard link to symlink tricks.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"PSF","cpe":[],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"In CPython 3.13 and earlier, the tarfile module's data and tar extraction filters are vulnerable to crafted archives containing a hard link to a symbolic link.
