Due to a flaw in the option parser for sending NEW_ENV variables, libcurl could be made to pass on uninitialized data from a stack based buffer to the server, resulting in potentially revealing sensitive internal information to the server using a clear-text network protocol.","published_at":"2021-06-11T15:49:37Z","last_modified_at":"2026-10-14T11:16:52.873000Z","cvss_v3_score":3.1,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N","cvss_v3_severity":"LOW","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"poc","ssvc_automatable":false,"ssvc_technical_impact":"partial","cwes":["CWE-200"],"nvd_references":["https://hackerone.com/reports/1176461","https://curl.se/docs/CVE-2021-22898.html","https://github.com/curl/curl/commit/39ce47f219b09c380b81f89fe54ac586c8db6bde","https://lists.apache.org/thread.html/rc713534b10f9daeee2e0990239fa407e2118e4aa9e88a7041177497c%40%3Cissues.guacamole.apache.org%3E","https://www.oracle.com//security-alerts/cpujul2021.html","http://www.openwall.com/lists/oss-security/2021/07/21/4","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/POOC3UV7V6L4CJ5KA2PTWTNUV5Y72T3Q/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FRUCW2UVNYUDZF72DQLFQR4PJEC6CF7V/","https://lists.debian.org/debian-lts-announce/2021/08/msg00017.html","https://www.oracle.com/security-alerts/cpujan2022.html","https://www.oracle.com/security-alerts/cpuapr2022.html","https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf","https://www.debian.org/security/2022/dsa-5197","https://lists.debian.org/debian-lts-announce/2022/08/msg00017.html"],"vuln_status":"Modified","trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-10-14T23:59:09.254433Z"},"effective_severity":"LOW","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack
