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-2025-62596 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- youki (crates.io): affected all versions; fixed in 0.5.7\n- youki (crates.io): affected all versions; fixed in 0.5.7\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-2025-62596/ (Markdown: https://insights.sbomify.com/CVE-2025-62596/index.md)","id":"CVE-2025-62596","markdown":"https://insights.sbomify.com/CVE-2025-62596/index.md","name":"CVE-2025-62596","record":{"aliases":["GHSA-vf95-55w6-qmrf"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Rust container runtime","requires_auth":"low_privilege","summary":"Attackers can escape containers or cause denial of service via arbitrary writes to procfs due to insufficient path validation in youki.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"youki","vendor":"youki-dev"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:A/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-61","name":"UNIX Symbolic Link (Symlink) Following"},{"id":"CWE-363","name":"Race Condition Enabling Link Following"}],"description":"Youki is a container runtime written in Rust.
