{"id":"CVE-2026-49146","summary":"App::Ack versions before 3.10.0 for Perl allow memory exhaustion via an unbounded context value in a project .ackrc","details":"App::Ack versions before 3.10.0 for Perl allow memory exhaustion via an unbounded context value in a project .ackrc.\n\nack searches up the directory hierarchy from the current directory for a project .ackrc and loads its options. The -B and -C context options accepted any positive integer, and ack sized the before-context buffer to that value, so a project .ackrc setting --before-context=100000000 made ack allocate a buffer of 100 million elements.\n\nA project .ackrc committed to an untrusted repository can abort ack with an out-of-memory condition.","modified":"2026-07-10T04:02:58.954466604Z","published":"2026-07-08T14:55:37.207Z","related":["openSUSE-SU-2026:10965-1"],"database_specific":{"cna_assigner":"CPANSec","cwe_ids":["CWE-770"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49146.json"},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/07/08/8"},{"type":"WEB","url":"https://cpan.org/modules"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49146.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-2026-49146"},{"type":"FIX","url":"https://github.com/beyondgrep/ack3/commit/45ff5fe77dbd96f7332f31943102291f878f30b8.patch"},{"type":"PACKAGE","url":"https://github.com/beyondgrep/ack3"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/beyondgrep/ack3","events":[{"introduced":"0"},{"fixed":"e627c18e77d635b0dad69c77749e9296071b8389"},{"fixed":"45ff5fe77dbd96f7332f31943102291f878f30b8"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.10.0"}],"source":["DESCRIPTION","REFERENCES"]}}],"versions":["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-2026-49146.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"}]}
