CVE-2016-9646: Commit metadata forgery via CGI::FormBuilder context-dependent APIs
First published: Thu Dec 29 2016(Updated: )
ikiwiki before 3.20161229 incorrectly called the CGI::FormBuilder->field method (similar to the CGI->param API that led to Bugzilla's CVE-2014-1572), which can be abused to lead to commit metadata forgery.
