DBI versions before 1.653 for Perl load arbitrary modules via unvalidated dbm_type and dbm_mldbm attributes in DBD::DBM. DBD::DBM passes the dbm_type and dbm_mldbm connect attributes to require without checking that the value names a module. require treats a path-shaped string as a literal filename and does not consult @INC, so the attribute chooses the file that Perl loads and runs. The MLDBM::Serializer:: prefix that DBD::DBM prepends to dbm_mldbm is not a boundary: only the :: separators are rewritten to /, so a value containing / traverses out of the serializer directory. The value is also assigned to $MLDBM::Serializer, which MLDBM requires the same way when it ties the table. A 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. For example, my $dsn = "dbi:DBM:f_dir=/var/db;dbm_type=../../Untrusted.pm" my $dbh = DBI->connect( $dsn ); Note that DBD::Gofer forwards connect attributes to the server side, and DBI::ProxyServer checks only that a DSN starts with a driver prefix.

    Vulnerabilities were discovered in libdbi-perl, the Perl Database     Interface (DBI), which may lead to memory corruption, denial of service,     or arbitrary module load.

    CVE-2026-78030

        Harsh Raj Singhania discovered that an attacker able to choose DSN         fragments or request parameter can trigger arbitrary module load due         to the lack of connect attribute validation.

    CVE-2026-88815

        Harsh Raj Singhania discovered that sql_type_cast_svpv() incorrectly         treats numeric values as strings, which may lead to application         crash.

    CVE-2026-88816

        Harsh Raj Singhania discovered that FetchHashKeyName incorrectly         treats numeric values as strings, which may lead to application         crash.

    For Debian 12 bookworm, these problems have been fixed in version     1.643-4+deb12u3.

    We recommend that you upgrade your libdbi-perl packages.
