Issue Overview:
An open redirect flaw was discovered in mod_auth_openidc, where it handles logout redirection. The module does not correctly validate the URL, allowing a URL with leading slashes to bypass the protection checks. A victim user may be tricked into visiting a trusted vulnerable web site, which would redirect them to another possibly malicious URL. (CVE-2019-14857)
