{"id":"UBUNTU-CVE-2026-49145","details":"App::Ack versions through 3.10.0 for Perl read arbitrary files via --files-from in a project .ackrc. ack 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. A project .ackrc committed to an untrusted repository can make ack read files outside the project and print their matching lines.","modified":"2026-07-15T19:47:26.161535558Z","published":"2026-07-08T15:16:00Z","upstream":["CVE-2026-49145"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-49145"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-49145"},{"type":"REPORT","url":"https://lists.security.metacpan.org/cve-announce/msg/41643327/"}],"affected":[{"package":{"name":"ack","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/ack?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.22-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.22-1","binary_name":"ack"},{"binary_name":"ack-grep","binary_version":"2.22-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-49145.json"}},{"package":{"name":"ack","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/ack?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.0.2-1","3.1.3-1","3.2.0-1","3.3.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"ack","binary_version":"3.3.1-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-49145.json"}},{"package":{"name":"ack","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/ack?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.0-1","3.5.0-1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.5.0-1","binary_name":"ack"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-49145.json"}},{"package":{"name":"ack","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/ack?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.7.0-1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.7.0-1","binary_name":"ack"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-49145.json"}},{"package":{"name":"ack","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/ack?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.7.0-1","3.8.1-1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.8.1-1","binary_name":"ack"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-49145.json"}},{"package":{"name":"ack","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/ack?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.8.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"ack","binary_version":"3.8.1-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-49145.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"},{"type":"Ubuntu","score":"medium"}]}
