{"id":"CVE-2026-126673","summary":"Data::Dump::Streamer versions before 3.00 for Perl allow code injection via unescaped Regexp patterns in _dump_qr","details":"Data::Dump::Streamer versions before 3.00 for Perl allow code injection via unescaped Regexp patterns in _dump_qr.\n\nA Regexp's pattern is written into a qr literal without escaping \"$\" or \"@\", so \"@{[ ... ]}\" and \"${\\ ... }\" in the pattern run as code when the dump is evaluated. An already escaped delimiter gets a second backslash, which leaves the delimiter bare and ends the qr literal early.\n\nAn attacker who supplies a pattern that an application compiles, dumps and later restores with eval or do can run arbitrary Perl code.","modified":"2026-11-13T02:47:10.356312499Z","published":"2026-11-12T00:44:34.065Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/126xxx/CVE-2026-126673.json","cna_assigner":"CPANSec","cwe_ids":["CWE-94"]},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/11/12/2"},{"type":"WEB","url":"https://cpan.org/modules"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/126xxx/CVE-2026-126673.json"},{"type":"ADVISORY","url":"https://metacpan.org/release/YVES/Data-Dump-Streamer-3.00/source/Changes"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-126673"},{"type":"PACKAGE","url":"https://github.com/demerphq/Data-Dump-Streamer"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/demerphq/data-dump-streamer","events":[{"introduced":"0"},{"fixed":"c457f61c51aaefd4948810c1eddacf558e820d0f"}],"database_specific":{"extracted_events":[{"strategy":"StandardRange","range":[{"introduced":"0"},{"fixed":"3.00"}],"source":"AFFECTED_FIELD"}]}}],"versions":["v2.41","v2.38","v2.37_02","v2.37_01","v2.37","v2.36","v2.34","v2.33","v2.32","v2.28","v2.27","v2.29","v2.31","v2.08","v2.09","v2.10","v2.11","v2.12","v2.13","v2.14","v2.15","v2.16","v2.17","v2.18","v2.19","v2.21","v2.22","v2.23","v2.24","v2.25","v2.26","v2.07","v1.04","v1.03","v1.05","v1.06","v1.07","v1.08","v1.09","v1.10","v1.11","v1.12","v1.14","v2.00","v2.01","v2.02","v2.03","v2.04","v2.05","v2.06","v1.0","v1.01","v1.02"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-126673.json"}}],"schema_version":"1.9.2"}
