{"id":"AZL-9909","summary":"CVE-2022-27780 affecting package curl for versions less than 7.83.1-1","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.","modified":"2026-04-01T05:23:46.773627Z","published":"2022-06-02T14:15:44Z","upstream":["CVE-2022-27780"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-27780"}],"affected":[{"package":{"name":"curl","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/curl"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.83.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-9909.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
