{"id":"DEBIAN-CVE-2026-11527","details":"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.  Config::IniFiles::_make_filehandle opens a filename argument with Perl's 2-arg open(), so a filename that begins or ends with a pipe (\"| cmd\", \"cmd |\") or begins with a redirect (\"\u003e path\", \"\u003e\u003e 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 =\u003e $thing) reaches it through ReadConfig. An in-memory scalar reference (-file =\u003e \\$text) does not open a path and is unaffected.  Any caller that forwards untrusted input to the -file argument can run an arbitrary command or truncate a file under the process UID.","modified":"2026-09-14T17:01:27.221293764Z","published":"2026-06-14T12:16:23.357Z","upstream":["CVE-2026-11527"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-11527"}],"affected":[{"package":{"name":"libconfig-inifiles-perl","ecosystem":"Debian:12","purl":"pkg:deb/debian/libconfig-inifiles-perl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.000003-2+deb12u1"}]}],"versions":["3.000003-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-11527.json"}},{"package":{"name":"libconfig-inifiles-perl","ecosystem":"Debian:13","purl":"pkg:deb/debian/libconfig-inifiles-perl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.000003-3+deb13u1"}]}],"versions":["3.000003-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-11527.json"}},{"package":{"name":"libconfig-inifiles-perl","ecosystem":"Debian:14","purl":"pkg:deb/debian/libconfig-inifiles-perl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.000003-5"}]}],"versions":["3.000003-3","3.000003-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-11527.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"}]}
