An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-32198 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/rancher/steve (Go): affected all versions; no fix listed\n- github.com/rancher/steve (Go): affected from 0.2.0; fixed in 0.2.1, 0.4.4, 0.5.13\n- github.com/rancher/steve (Go): affected from 0.2.0; fixed in 0.2.1\n- github.com/rancher/steve (Go): affected from 0.2.0; fixed in 0.2.1\n- github.com/rancher/steve (Go): affected from 0.3.0; fixed in 0.3.3\n- github.com/rancher/steve (Go): affected from 0.3.0; fixed in 0.3.3\n- github.com/rancher/steve (Go): affected from 0.4.0; fixed in 0.4.4\n- github.com/rancher/steve (Go): affected from 0.4.0; fixed in 0.4.4\n- github.com/rancher/steve (Go): affected from 0.5.0; fixed in 0.5.13\n- github.com/rancher/steve (Go): affected from 0.5.0; fixed in 0.5.13\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-2023-32198/ (Markdown: https://insights.sbomify.com/CVE-2023-32198/index.md)","id":"CVE-2023-32198","markdown":"https://insights.sbomify.com/CVE-2023-32198/index.md","name":"CVE-2023-32198","record":{"aliases":["GHSA-95fc-g4gj-mqmx","GO-2025-3648"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Go TLS library","requires_auth":"high_privilege","summary":"Steve library fails to validate server certificates by default, enabling man-in-the-middle attacks against services using it.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"suse","cpe":[],"cvss":{"score":8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"A vulnerability has been identified in Steve where by default it was using an insecure option that did not validate the certificate presented by the remote server while performing a TLS connection.
