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-2026-106070/ (Markdown: https://insights.sbomify.com/CVE-2026-106070/index.md)","id":"CVE-2026-106070","markdown":"https://insights.sbomify.com/CVE-2026-106070/index.md","name":"CVE-2026-106070","record":{"aliases":["ALPINE-CVE-2026-106070","BIT-node-2026-106070","BIT-node-min-2026-106070","GHSA-c2qw-fgxm-vxx4","UBUNTU-CVE-2026-106070"],"analysis":null,"analysis_generated_by":null,"assigner":"hackerone","cpe":[],"cvss":{"score":3.7,"severity":"low","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-840","name":null}],"description":"A flaw in the Node.js `zlib.ZipFile` API can cause it to return bytes that do not belong to the requested entry after the local and central header validation fails.\n\nWhen `zipEntry.modified` is read on an archive whose local header does not match its central directory, either directly or while compacting the archive, the validation error is caught but the parsed local header is left cached without a content offset.
