Descripción técnica

CGI versions before 5.00 for Perl allow open redirects and script injection via URLs built from REQUEST_URI in url and start_form. url(-absolute=>1), url(-relative=>1) and the default start_form action are built from the client-supplied REQUEST_URI without validation. 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.

———CGI versions before 5.00 for Perl allow HTML injection via text containing --> in comment. Arguments are placed between  without escaping, so text containing --> closes the comment early. An application that passes request data to comment can be made to inject HTML into the page.7h CVE-2026-120643—

———CGI versions from 4.62 before 5.00 for Perl allow cross-site scripting via a raw apostrophe in URLs returned by url and self_url. Both pass the URL through URI's canonical method, which leaves an apostrophe in the path raw and decodes the %27 that query parameter escaping produces, so an apostrophe in the request path or a parameter appears raw in the result. An application that places the URL in a single-quoted HTML attribute or JavaScript string is open to cross-site scripting.7h CVE-2026-120638—

———CGI versions before 5.00 for Perl allow open redirects via HTML entity decoding of the URL after application validation in redirect. redirect decodes HTML entities in its URL before writing the Location header, so a URL the application has already validated can change meaning. For example, //evil.example/ becomes //evil.example/ and sends the user to another host.7h CVE-2026-120633—

———CGI versions before 5.00 for Perl trust the client X-Forwarded-Host header in url, self_url, virtual_host and virtual_port. These 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=>1) base href, and the default start_form action when REQUEST_URI is not set. A client can poison shared caches, and URLs the application stores or sends, with redirects, links and scripts that point at a host it controls.7h CVE-2026-115541—

———HumHub Community Edition 1.19.0 contains a stored cross-site scripting vulnerability in the friendship confirmation dialog. An authenticated low-privileged member can save HTML in their first and last name. When another authenticated user clicks Friends for that profile, HumHub places the decoded display name into a modal through jQuery html(), causing attacker-controlled markup to execute in the victim's HumHub origin.9h CVE-2026-821616.8 MED
