An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-3762 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/quay/claircore (Go): affected all versions; fixed in 0.4.8\n- github.com/quay/claircore (Go): affected all versions; fixed in 0.4.8\n- github.com/quay/claircore (Go): affected all versions; fixed in 1.1.0\n- github.com/quay/claircore (Go): affected from 0.5.0; fixed in 0.5.5\n- github.com/quay/claircore (Go): affected from 0.5.0; fixed in 0.5.5\n- github.com/quay/claircore (Go): affected from 1.0.0; fixed in 1.1.0\n- github.com/quay/claircore (Go): affected from 1.0.0; fixed in 1.1.0\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-2021-3762/ (Markdown: https://insights.sbomify.com/CVE-2021-3762/index.md)","id":"CVE-2021-3762","markdown":"https://insights.sbomify.com/CVE-2021-3762/index.md","name":"CVE-2021-3762","record":{"aliases":["GHSA-mq47-6wwv-v79w","GO-2022-0346"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Clair container scanner","requires_auth":"none","summary":"An attacker can achieve arbitrary file write and potential remote code execution by supplying a crafted container image to the Clair scanner.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"clair","vendor":"redhat"},{"product":"quay","vendor":"redhat"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"A directory traversal vulnerability was found in the ClairCore engine of Clair.
