{"id":"CVE-2026-58139","summary":"DuckDB AWS Extension Security Policy Bypass via load_aws_credentials Procedure","details":"The DuckDB AWS extension for DuckDB contains a security policy bypass vulnerability that allows any database user with SQL execution permissions to extract plaintext AWS credentials by calling the load_aws_credentials function with the redact_secret parameter set to false, circumventing the database-wide allow_unredacted_secrets=false policy. Attackers can invoke this single function to retrieve the underlying AWS credential chain including access_key_id, secret_access_key, session_token, and region in plaintext, which are immediately valid against AWS APIs and particularly impactful in managed environments where pg_duckdb is preloaded and an AWS credential chain such as IMDSv2, IRSA, ECS task role, or EC2 instance role is reachable.","modified":"2026-08-15T04:07:09.748254129Z","published":"2026-08-03T19:45:31.730Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/58xxx/CVE-2026-58139.json","unresolved_ranges":[{"extracted_events":[{"fixed":"7d04119ee8d3f8836e278f0e8cbf21827ff5338b"}],"source":"AFFECTED_FIELD"}],"cna_assigner":"VulnCheck","cwe_ids":["CWE-863"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/58xxx/CVE-2026-58139.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58139"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/duckdb-aws-extension-security-policy-bypass-via-load-aws-credentials-procedure"},{"type":"REPORT","url":"https://github.com/duckdb/duckdb-aws/pull/156"},{"type":"FIX","url":"https://github.com/duckdb/duckdb-aws/commit/7d04119ee8d3f8836e278f0e8cbf21827ff5338b"},{"type":"PACKAGE","url":"https://github.com/duckdb/duckdb-aws"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/duckdb/duckdb-aws","events":[{"introduced":"0"},{"fixed":"7d04119ee8d3f8836e278f0e8cbf21827ff5338b"}],"database_specific":{"source":"REFERENCES"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-58139.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
