It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-93315 in the wild and no public exploit code.\n\nAffected product: moby BuildKit. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-93315/ (Markdown: https://insights.sbomify.com/CVE-2026-93315/index.md)","id":"CVE-2026-93315","markdown":"https://insights.sbomify.com/CVE-2026-93315/index.md","name":"CVE-2026-93315","record":{"aliases":["BELL-CVE-2026-93315","GHSA-2f5p-x9ph-g97x","UBUNTU-CVE-2026-93315"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"patch","impacts":["denial_of_service","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"BuildKit container builder","requires_auth":"low_privilege","summary":"Attackers can disrupt BuildKit proxy CA cleanup via race conditions, potentially blocking builds or bypassing security controls.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Docker","cpe":[],"cvss":{"score":5.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:H/SC:N/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"}],"description":"When proxy networking with CA injection is enabled, a build can modify its CA bundle before cleanup.
