CVE-2026-11527

Config::IniFiles versions before 3.001000 for Perl allow OS command injection and file overwrite via a 2-arg open() of the -file argument in _make_filehandle.<br /> <br /> Config::IniFiles::_make_filehandle opens a filename argument with Perl&amp;#39;s 2-arg open(), so a filename that begins or ends with a pipe ("| cmd", "cmd |") or begins with a redirect ("&gt; path", "&gt;&gt; path") is run as a command or redirect rather than opened as a file. The helper is the open path behind the documented -file argument: new(-file =&gt; $thing) reaches it through ReadConfig. An in-memory scalar reference (-file =&gt; \$text) does not open a path and is unaffected.<br /> <br /> Any caller that forwards untrusted input to the -file argument can run an arbitrary command or truncate a file under the process UID.
