{"id":"ALPINE-CVE-2026-49145","details":"App::Ack versions through 3.10.0 for Perl read arbitrary files via --files-from in a project .ackrc.\n\nack searches up the directory hierarchy from the current directory for a project .ackrc and loads its options. The project-source option blocklist in App::Ack::ConfigLoader does not include --files-from, so a project .ackrc can set it to a path whose listed files ack then reads and searches. Version 3.10.0 added --follow to the blocklist; --files-from remains accepted.\n\nA project .ackrc committed to an untrusted repository can make ack read files outside the project and print their matching lines.","modified":"2026-09-14T16:18:08.215972453Z","published":"2026-07-08T15:16:27.563Z","upstream":["CVE-2026-49145"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-49145"}],"affected":[{"package":{"name":"ack","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/ack?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.10.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-49145.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
