The value is also assigned to $MLDBM::Serializer, which MLDBM requires the same way when it ties the table.\n\nA caller that lets an untrusted party influence either attribute, for example through a DSN fragment or a parameter that selects a storage backend, runs the file-scope code of whatever module the value names.\n\nFor example,\n\n    my $dsn = \"dbi:DBM:f_dir=/var/db;dbm_type=../../Untrusted.pm\"\n    my $dbh = DBI->connect( $dsn );\n\nNote that DBD::Gofer forwards connect attributes to the server side, and DBI::ProxyServer checks only that a DSN starts with a driver prefix."}],"problemTypes":[{"descriptions":[{"cweId":"CWE-470","description":"CWE-470 Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection')","lang":"en","type":"CWE"}]}],"providerMetadata":{"orgId":"9b29abf9-4ab0-4765-b253-1875cd9b441e","shortName":"CPANSec","dateUpdated":"2026-09-19T10:45:10.164Z"},"references":[{"tags":["release-notes"],"url":"https://metacpan.org/release/HMBRAND/DBI-1.653/changes"},{"tags":["patch"],"url":"https://github.com/perl5-dbi/dbi/commit/315c6ce703b8b3cbe9188062d9ec80730293554a.patch"},{"tags":["vendor-advisory"],"url":"https://github.com/perl5-dbi/dbi/security/advisories/GHSA-wqmw-wqwx-3fr7"}],"solutions":[{"lang":"en","value":"Upgrade to DBI version 1.653 or later, or apply the upstream patch."}],"source":{"discovery":"UNKNOWN"},"title":"DBI versions before 1.653 for Perl load arbitrary modules via unvalidated dbm_type and dbm_mldbm attributes in DBD::DBM","x_generator":{"engine":"cpansec-cna-tool 0.1"}},"adp":[{"title":"CVE Program Container","references":[{"url":"http://www.openwall.com/lists/oss-security/2026/09/19/4"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2026-09-19T18:07:55.310Z"}},{"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":9.8,"attackVector":"NETWORK","baseSeverity":"CRITICAL","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","integrityImpact":"HIGH","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"NONE","confidentialityImpact":"HIGH"}},{"other":{"type":"ssvc","content":{"timestamp":"2026-09-20T00:05:25.993244Z","id":"CVE-2026-78030","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-20T00:05:29.533Z"}}]}}
