{"id":"AZL-112798","summary":"CVE-2026-120633 affecting package perl-CGI 4.60-1","details":"CGI versions before 5.00 for Perl trust the client X-Forwarded-Host header in url, self_url, virtual_host and virtual_port.\n\nThese take the host name and port from the X-Forwarded-Host request header when present, and otherwise from Host, without validating either. The URLs from url and self_url are the default redirect location and the start_html(-base=\u003e1) base href, and the default start_form action when REQUEST_URI is not set.\n\nA client can poison shared caches, and URLs the application stores or sends, with redirects, links and scripts that point at a host it controls.","modified":"2026-11-07T14:18:07.188900103Z","published":"2026-11-04T00:17:24Z","upstream":["CVE-2026-120633"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-120633"}],"affected":[{"package":{"name":"perl-CGI","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/perl-CGI"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"4.60-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-112798.json"}}],"schema_version":"1.9.2"}
