The result can be protocol-relative (//evil.example), absolute-form (http://evil.example/) or contain backslashes, and url(-relative=>1) can return a javascript: URL. Links and form posts built from these URLs can go to another host.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-79","CWE-601"],"vendors":[],"products":[],"references":[{"url":"https://github.com/leejo/CGI.pm/commit/9405ef3909ee94991a3474167aa53b9051bd8765.patch","tags":[]},{"url":"https://metacpan.org/release/LEEJO/CGI-4.72/source/lib/CGI.pm","tags":[]},{"url":"https://metacpan.org/release/LEEJO/CGI-5.00/changes","tags":[]}],"exploitRefs":[{"url":"https://github.com/leejo/CGI.pm/commit/9405ef3909ee94991a3474167aa53b9051bd8765.patch","tags":[]}],"hasPoc":true,"ai":null}
