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-2026-76227 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- renovate (npm): affected from 42.68.1; fixed in 42.96.3\n- renovate (npm): affected from 42.68.1; fixed in 42.96.3\n- renovate (npm): affected from 43.0.0; fixed in 43.4.4\n- renovate (npm): affected from 43.0.0; fixed in 43.4.4\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-2026-76227/ (Markdown: https://insights.sbomify.com/CVE-2026-76227/index.md)","id":"CVE-2026-76227","markdown":"https://insights.sbomify.com/CVE-2026-76227/index.md","name":"CVE-2026-76227","record":{"aliases":["CLEANSTART-2026-BQ28777","GHSA-8wc6-vgrq-x6cf","GHSA-p44v-39mg-jgrj"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Renovate dependency updater","requires_auth":"low_privilege","summary":"Attackers can exfiltrate secrets from environment variables because child processes inherit all variables without restriction.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-526","name":"Cleartext Storage of Sensitive Information in an Environment Variable"}],"description":"Renovate versions from 42.68.1 before 42.96.3 and from 43.0.0 before 43.4.4, including the renovate/renovate Docker images, and Mend Renovate CE/EE images (renovate-ce, renovate-ee-server, renovate-ee-worker) from 13.3.0 before 13.6.0, fail to restrict environment variables to an allowlist when spawning child processes.
