{"id":"ALPINE-CVE-2026-49147","details":"App::Ack versions through 3.10.0 for Perl print unsanitised terminal escape sequences from filenames in several output modes.\n\nWhen ack prints a filename whose basename contains terminal control bytes such as ANSI escape sequences, those bytes reach the terminal unchanged. Version 3.10.0 added a _safe_filename helper that sanitises the filenames printed by -f, -g, the colored match heading, and per-match lines, but the --show-types, -l/-L, and -c paths still emit the raw filename.\n\nA file whose name embeds cursor-movement or color escapes can overwrite or recolor earlier terminal output, or be passed unchanged to a downstream consumer.","modified":"2026-09-14T16:18:08.216595427Z","published":"2026-07-08T15:16:27.787Z","upstream":["CVE-2026-49147"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-49147"}],"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-2026-49147.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"}]}
