Its retrieve_subject_token sends requests to the imdsv2_session_token_url, url and region_url fields of credential_source without the host check that the other credential classes apply.\n\nAny caller that builds credentials from a configuration it does not fully control issues GET and PUT requests to hosts the configuration names, including internal services and link-local metadata endpoints.","epss":null,"exploits":[],"kev":null,"metrics":[],"modifiedAt":1793553394280,"publishedAt":1793553394280,"references":[{"source":"9b29abf9-4ab0-4765-b253-1875cd9b441e","tags":[],"url":"https://metacpan.org/release/CJCOLLIER/Google-Auth-0.12/source/lib/Google/Auth/ExternalAccountCredentials/Aws.pm"}],"remediation":[],"revision":"77bc58ce262602a38147cc45c9783433262c0534cb64a161dc8fe0496b50aa94","sources":[{"modifiedAt":1793553394280,"name":"NVD","retrievedAt":1793578577770,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74759"}],"ssvc":null,"status":"published","title":"CVE-2026-74759","updatedAt":1793578577770}
