UBUNTU-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,...

UBUNTU-CVE-2026-120646

CGI versions from 4.71 before 5.00 for Perl allow denial of service via a plain string dereferenced as a symbolic reference in uploadInfo. uploadInfo dereferences its argument and calls its filename method without checking that it is an upload filehandle. A plain string naming a defined global...

UBUNTU-CVE-2026-120631

CGI::Cookie versions from 4.67 before 5.00 for Perl allow denial of service via the client cookie expires value used as a regex in parse. CGI's cookie method reads the Cookie request header through parse, which interpolates the header's expires value unescaped into the substitution pattern that...

UBUNTU-CVE-2026-120633

CGI versions before 5.00 for Perl trust the client X-Forwarded-Host header in url, selfurl, virtualhost and virtualport. 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 selfurl are t...

UBUNTU-CVE-2026-120648

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...

UBUNTU-CVE-2026-120642

CGI versions before 5.00 for Perl return request-derived values untainted under taint mode. The upload filename, uploadInfo values, some pathinfo and scriptname values, Accept results, and the name lists from urlparam and cookie are returned without the taint flag, as is a cookie named expires fr...

UBUNTU-CVE-2026-120651

CGI versions before 5.00 for Perl allow an infinite loop on a short request body when $DISABLEUPLOADS is set. When $CGI::PUTDATAUPLOAD or an upload hook is set, readpostdataputdata takes a request body that is not a form submission. With $CGI::DISABLEUPLOADS set, it discards the body by reading...

UBUNTU-CVE-2026-120636

CGI versions before 5.00 for Perl allow open redirects and script injection via URLs built from REQUESTURI in url and startform. url-absolute=1, url-relative=1 and the default startform action are built from the client-supplied REQUESTURI without validation. The result can be protocol-relative...

UBUNTU-CVE-2026-120634

CGI::Carp versions before 5.00 for Perl leak warnings across requests in persistent environments via the warningsToBrowser buffer. Warnings are held in a package-level buffer until warningsToBrowser writes them into the page as HTML comments, and the buffer is never cleared between requests. Unde...

UBUNTU-CVE-2026-120637

CGI versions before 5.00 for Perl take request parameters from the process command line arguments for an unrecognised REQUESTMETHOD. For a REQUESTMETHOD such as OPTIONS, CGI falls through to its offline debugging mode, which is on by default, and builds the parameters and pathinfo from the...
