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-2021-30476 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-30476/ (Markdown: https://insights.sbomify.com/CVE-2021-30476/index.md)","id":"CVE-2021-30476","markdown":"https://insights.sbomify.com/CVE-2021-30476/index.md","name":"CVE-2021-30476","record":{"aliases":["GHSA-23fv-m8pv-77j9"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Terraform Vault Provider","requires_auth":"none","summary":"Attackers can bypass authentication in HashiCorp Vault's GCP auth method due to incorrect GCE bound label configuration in the Terraform provider.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"terraform_provider","vendor":"hashicorp"}],"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":[],"description":"HashiCorp Terraform’s Vault Provider (terraform-provider-vault) did not correctly configure GCE-type bound labels for Vault’s GCP auth method.
