CVE-2026-15747

Mojolicious versions from 4.59 before 9.48 for Perl expose a stable representation of the session CSRF token to a BREACH compression oracle. csrftoken generates and caches one token per session and returns the same value on every call, and csrffield places that value in a hidden csrftoken input...

CVE-2026-60082 DBI versions before 1.651 for Perl do not enforce statement handle consistency with the row

DBI versions before 1.651 for Perl do not enforce statement handle consistency with the row. When the statement handle had no fields but the source row was non-empty, the internal row-buffer helper would read from a negative array index. This could be triggered by a caller supplying inconsistent...

CVE-2026-60081 DBI::ProfileData versions before 1.651 for Perl do not limit the path index

DBI::ProfileData versions before 1.651 for Perl do not limit the path index. The path index column of profile dump files is used to allocate an array of data for the parser. An unbounded value allows an attacker to specify a large index and consume available memory...

CVE-2026-60081

The provided data indicate a memory‑consumption risk in DBI::ProfileData prior to version 1.651 for Perl. The issue arises from an unbounded path index in profile dump files, which can be used to allocate an excessively large array and exhaust memory. Affected component: DBI::ProfileData (Perl). ...

CVE-2026-15392 DBD::File versions before 1.651 for Perl do not ensure the table file is not a symlink to an untrusted location

DBD::File versions before 1.651 for Perl do not ensure the table file is not a symlink to an untrusted location. The completetablename method builds the absolute table file path without checking whether the file is a symbolic link. A link inside the data directory can point to a table file at any...

CVE-2026-15043

CVE-2026-15043 affects DBI::SQL::Nano (versions 1.42–1.650.x) for Perl. In the non-numeric string branch of is_matched, the = with Perl's le, causing inverted = comparisons in WHERE predicates. This occurs in the fallback SQL engine used by DBI's file-backed drivers (e.g., DBD::File, DBD::DBM, CS...

EUVD-2026-43574

Crypt::OpenSSL::X509 versions before 2.1.3 for Perl allow a heap out-of-bounds read via a long certificate extension OID in hvexts. When building the extension hash via extensions, extensionsbylongname, extensionsbyoid, or hasextensionoid, the code passes OBJobj2txt's return value as the hash-key...

EUVD-2026-43573

Crypt::OpenSSL::X509 versions before 2.1.3 for Perl allow denial of service via NULL pointer dereference. X509V3EXTd2iext returns NULL when an extension's DER value fails to parse. basicC, ia5string, and authatt dereference its result without a NULL check. keyiddata also dereferences akid-keyid,...

CVE-2026-57432

Perl versions through 5.43.10 have an integer overflow in Smeasurestruct leading to an out-of-bounds heap read in pack and unpack. Smeasurestruct adds each item's size times its repeat count to a running total with no overflow check, so a large repeat count in a pack or unpack template wraps the...

CVE-2026-57433

Storable versions before 3.41 for Perl have a signed integer overflow when deserializing a crafted SXHOOK record. retrievehookcommon reads a signed 32-bit item count from an SXHOOK record and calls avextend with that count plus one. A count of I32MAX wraps the addition to a negative value. A...
