Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-11621 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/hashicorp/vault (Go): affected from 0.6.0; fixed in 1.21.0\n- github.com/hashicorp/vault (Go): affected from 0.6.0; fixed in 1.21.0\n- github.com/hashicorp/vault (Go): affected from 0.6.0; fixed in 1.21.0\n- vault (Bitnami): affected from 0.6.0; fixed in 1.21.0\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-2025-11621/ (Markdown: https://insights.sbomify.com/CVE-2025-11621/index.md)","id":"CVE-2025-11621","markdown":"https://insights.sbomify.com/CVE-2025-11621/index.md","name":"CVE-2025-11621","record":{"aliases":["BIT-vault-2025-11621","GHSA-9g4h-h484-3578","GO-2025-4070","MINI-w34j-hg35-wmg4"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"HashiCorp Vault","requires_auth":"low_privilege","summary":"Attackers can bypass AWS authentication in HashiCorp Vault if bound_principal_iam roles are identical across accounts or use wildcards.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HashiCorp","cpe":[{"product":"vault","vendor":"hashicorp"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"Vault and Vault Enterprise’s (“Vault”) AWS Auth method may be susceptible to authentication bypass if the role of the configured bound_principal_iam is the same across AWS accounts, or uses a wildcard.
