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/RUSTSEC-2020-0169/ (Markdown: https://insights.sbomify.com/RUSTSEC-2020-0169/index.md)","id":"RUSTSEC-2020-0169","markdown":"https://insights.sbomify.com/RUSTSEC-2020-0169/index.md","name":"RUSTSEC-2020-0169","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["other"],"network_reachable":"unknown","non_default_config":false,"product_category":"Rust library","requires_auth":"none","summary":"The unmaintained multi_mut crate has an unresolved soundness issue causing undefined behavior, requiring developers to migrate away from it.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Last release was about 6 years ago.\n\nThere is an outstanding [soundness issue](https://github.com/golddranks/multi_mut/issues/1).\n\nThe maintainer has not responded for two years to the existing soundness issue.\n\nRust compiler has enabled errors relating to LLVM noalias rules and may not\ncompile anymore where as the old compiler versions had turned these off.\n\nThe maintainer has stated:\n\n\u003e I will take no responsibility of undefined behaviour possibly caused by this crate.\n\nThis crate may or may not be suitable for use anymore given the outstanding issues.","ecosystems":["crates.io"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"multi_mut is Unmaintained","id":"RUSTSEC-2020-0169","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"other","year":"2020"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"crates.io","fixed":[],"introduced":["0.0.0-0"],"last_affected":[],"package":"multi_mut","purl":"pkg:cargo/multi_mut","source":"RUSTSEC-2020-0169"}],"products":null,"published":"2020-02-07","related":[],"sources":[{"class":"open","licence":"CC0 1.0","name":"RustSec","prefix":"RUSTSEC"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"The unmaintained multi_mut crate has an unresolved soundness issue causing undefined behavior, requiring developers to migrate away from it.","url":"https://insights.sbomify.com/RUSTSEC-2020-0169/"}
