{"id":"AZL-112807","summary":"CVE-2026-120640 affecting package perl-CGI 4.60-1","details":"CGI versions before 5.00 for Perl allow the POSTDATA, PUTDATA, PATCHDATA and XForms:Model parameters to be set from the query string or form fields.\n\nCGI stores a non-form request body under POSTDATA, PUTDATA or PATCHDATA, and an XForms body under XForms:Model, but also accepts these names from the query string, a form field or a multipart part, so an application cannot tell a client-sent value from the real body.\n\nA cross-site HTML form can post POSTDATA={\"admin\":true} to an endpoint that reads JSON from param('POSTDATA'), a request forgery that needs no CORS preflight.","modified":"2026-11-07T14:18:05.481348113Z","published":"2026-11-04T00:17:25Z","upstream":["CVE-2026-120640"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-120640"}],"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-112807.json"}}],"schema_version":"1.9.2"}
