{"id":"CVE-2026-49147","summary":"App::Ack versions through 3.10.0 for Perl print unsanitised terminal escape sequences from filenames in several output modes","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":"2026-07-10T04:02:59.148535317Z","published":"2026-07-08T14:55:50.232Z","related":["openSUSE-SU-2026:10965-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49147.json","cna_assigner":"CPANSec","cwe_ids":["CWE-150"]},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/07/08/9"},{"type":"WEB","url":"https://cpan.org/modules"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49147.json"},{"type":"ADVISORY","url":"https://metacpan.org/release/PETDANCE/ack-v3.10.0/source/Changes"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49147"},{"type":"PACKAGE","url":"https://github.com/beyondgrep/ack3"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/beyondgrep/ack3","events":[{"introduced":"0"},{"last_affected":"e627c18e77d635b0dad69c77749e9296071b8389"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"3.10.0"}]}}],"versions":["v3.10.0","v3.9.0","v3.8.2","v3.8.1","v3.8.0","v3.6.0","v3.5.0","v3.4.0","v3.1.3","v3.1.2","v3.1.1","v3.1.0","v3.0.3","v3.0.2","v3.0.1","v3.0.0","2.999_08","2.999_07","2.999_06","2.999_05","2.999_04","2.999_02","2.999_01","2.18r","2.18"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-49147.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
