{"id":"ALPINE-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.\n\nConfig::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.\n\nAny caller that forwards untrusted input to the -file argument can run an arbitrary command or truncate a file under the process UID.","modified":"2026-09-14T16:18:08.101285198Z","published":"2026-06-14T12:16:23.357Z","upstream":["CVE-2026-11527"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-11527"}],"affected":[{"package":{"name":"perl-config-inifiles","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/perl-config-inifiles?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.002000-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-11527.json"}},{"package":{"name":"perl-config-inifiles","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/perl-config-inifiles?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.002000-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-11527.json"}},{"package":{"name":"perl-config-inifiles","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/perl-config-inifiles?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.002000-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-11527.json"}},{"package":{"name":"perl-config-inifiles","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/perl-config-inifiles?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.002000-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-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"}]}
