{"id":"CVE-2022-27780","details":"The curl URL parser wrongly accepts percent-encoded URL separators like '/'when decoding the host name part of a URL, making it a *different* URL usingthe wrong host name when it is later retrieved.For example, a URL like `http://example.com%2F127.0.0.1/`, would be allowed bythe parser and get transposed into `http://example.com/127.0.0.1/`. This flawcan be used to circumvent filters, checks and more.","aliases":["CURL-CVE-2022-27780"],"modified":"2026-08-12T03:51:44.218588786Z","published":"2022-06-01T00:00:00Z","related":["openSUSE-SU-2024:12062-1"],"database_specific":{"unresolved_ranges":[{"extracted_events":[{"introduced":"Fixed in 7.83.1"},{"last_affected":"Fixed in 7.83.1"}],"source":"AFFECTED_FIELD"}],"cna_assigner":"hackerone","cwe_ids":["CWE-177"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/27xxx/CVE-2022-27780.json"},"references":[{"type":"WEB","url":"https://hackerone.com/reports/1553841"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/27xxx/CVE-2022-27780.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-27780"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202212-01"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20220609-0009/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/curl/curl","events":[{"introduced":"9e560d11aad028de74addc0d1edfefa5667884f4"},{"fixed":"462196e6b4a47f924293a0e26b8e9c23d37ac26f"}],"database_specific":{"source":"CPE_RANGE","cpe":"cpe:2.3:a:haxx:curl:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"7.80.0"},{"fixed":"7.83.1"}]}}],"versions":["curl-7_83_0","curl-7_82_0","curl-7_81_0","curl-7_80_0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-27780.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"}]}
