An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-4166 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/hashicorp/vault (Go): affected from 0.3.0; fixed in 1.19.3\n- github.com/hashicorp/vault (Go): affected from 0.3.0; fixed in 1.19.3\n- github.com/hashicorp/vault (Go): affected from 0.3.0; fixed in 1.19.3\n- openbao (Bitnami): affected all versions; fixed in 2.2.2\n- vault (Bitnami): affected from 0.3.0; fixed in 1.19.3\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-2025-4166/ (Markdown: https://insights.sbomify.com/CVE-2025-4166/index.md)","id":"CVE-2025-4166","markdown":"https://insights.sbomify.com/CVE-2025-4166/index.md","name":"CVE-2025-4166","record":{"aliases":["BIT-openbao-2025-4166","BIT-vault-2025-4166","GHSA-gcqf-f89c-68hv","GO-2025-3663","openSUSE-SU-2025:15186-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"HashiCorp Vault","requires_auth":"high_privilege","summary":"Attackers can expose sensitive data in logs by submitting malformed payloads to the KV v2 plugin, requiring an upgrade to Vault.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HashiCorp","cpe":[{"product":"vault","vendor":"hashicorp"},{"product":"openbao","vendor":"openbao"}],"cvss":{"score":4.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-209","name":"Generation of Error Message Containing Sensitive Information"}],"description":"Vault Community and Vault Enterprise Key/Value (kv) Version 2 plugin may unintentionally expose sensitive information in server and audit logs when users submit malformed payloads during secret creation or update operations via the Vault REST API.
