{"cve":"CVE-2025-59048","nvd":{"published":"2025-10-23T16:16:43.190","modified":"2026-10-08T11:10:00.250","status":"Analyzed","description":"OpenBao's AWS Plugin generates AWS access credentials based on IAM policies. Prior to version 0.1.1, the AWS Plugin is vulnerable to cross-account IAM role Impersonation in the AWS auth method. The vulnerability allows an IAM role from an untrusted AWS account to authenticate by impersonating a role with the same name in a trusted account, leading to unauthorized access. This impacts all users of the auth-aws plugin who operate in a multi-account AWS environment where IAM role names may not be unique across accounts. This vulnerability has been patched in version 0.1.1 of the auth-aws plugin. A workaround for this issue involves guaranteeing that IAM role names are unique across all AWS accounts that could potentially interact with your OpenBao environment, and to audit for any duplicate IAM roles.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","score":8.1},"cwes":["CWE-694","CWE-863"],"references":["https://github.com/openbao/openbao-plugins/commit/2a77af36834746ca6d3ac9bd1049154c84b3efae","https://github.com/openbao/openbao-plugins/security/advisories/GHSA-jp7h-4f3c-9rc7"],"products":["openbao:aws_plugin"],"source":"nvd","synced_at":"2026-10-19T22:12:35.277909958+00:00"},"epss":{"cve":"CVE-2025-59048","score":0.00266,"percentile":0.18313,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-jp7h-4f3c-9rc7","url":"https://osv.dev/vulnerability/GHSA-jp7h-4f3c-9rc7","summary":"OpenBao AWS Plugin Vulnerable to Cross-Account IAM Role Impersonation in AWS Auth Method","modified":"2025-11-05T19:57:32.120907Z","packages":[{"ecosystem":"Go","name":"github.com/openbao/openbao-plugins","purl":"pkg:golang/github.com/openbao/openbao-plugins","ranges":["<0.1.1"],"fixed":["0.1.1"]}]},{"id":"GO-2025-4067","url":"https://osv.dev/vulnerability/GO-2025-4067","summary":"OpenBao AWS Plugin Vulnerable to Cross-Account IAM Role Impersonation in AWS Auth Method in github.com/openbao/openbao-plugins","modified":"2025-11-05T19:57:32.120907Z","packages":[{"ecosystem":"Go","name":"github.com/openbao/openbao-plugins","purl":"pkg:golang/github.com/openbao/openbao-plugins","ranges":["all versions"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
