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-2026-54545 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @wakaru/cli (npm): affected from 1.0.0; fixed in 1.4.0\n- @wakaru/cli (npm): affected from 1.0.0; fixed in 1.4.0\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-2026-54545/ (Markdown: https://insights.sbomify.com/CVE-2026-54545/index.md)","id":"CVE-2026-54545","markdown":"https://insights.sbomify.com/CVE-2026-54545/index.md","name":"CVE-2026-54545","record":{"aliases":["GHSA-7wpj-vvmv-pgm8"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"JavaScript decompiler CLI","requires_auth":"none","summary":"Attackers can write files outside the output directory via crafted filenames in malicious bundles, potentially achieving code execution when users unpack them.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"wakaru is a JavaScript decompiler and unminifier toolkit.
