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/GHSA-48m6-wm5p-rr6h/ (Markdown: https://insights.sbomify.com/GHSA-48m6-wm5p-rr6h/index.md)","id":"GHSA-48m6-wm5p-rr6h","markdown":"https://insights.sbomify.com/GHSA-48m6-wm5p-rr6h/index.md","name":"GHSA-48m6-wm5p-rr6h","record":{"aliases":["RUSTSEC-2023-0070"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"unknown","non_default_config":false,"product_category":"Rust self_cell library","requires_auth":"none","summary":"Insufficient covariance checks in the self_cell library allow safe code to trigger undefined behavior, potentially leading to memory corruption and code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"All public versions prior to `1.02` used an insufficient check to ensure that\nusers correctly marked the dependent type as either `covariant` or\n`not_covariant`.
