CVE-2026-9516

A flaw was found in Cpanel::JSON::XS, a Perl module used for processing JSON data. This vulnerability allows a remote attacker to cause a denial of service DoS by providing specially crafted input that begins with a UTF-8 Byte Order Mark BOM. When a decode filter callback encounters an error with...

CVE-2026-9334

A flaw was found in perl-Cpanel-JSON-XS. This vulnerability allows a remote attacker to cause a denial of service DoS by providing specially crafted JSON input with duplicate object keys. When the dupkeysasarrayref option is enabled, the decodehv function incorrectly processes the input, leading ...

CVE-2026-9334

Cpanel::JSON::XS versions before 4.41 for Perl allow type confusion via duplicate object keys when dupkeysasarrayref is enabled. decodehv collapses duplicate object keys into an array reference under dupkeysasarrayref. The branch reached for a duplicate key tests SvTYPE oldvalue != SVtRV && SvTYP...

CVE-2026-9516

CVE-2026-9516 affects Cpanel::JSON::XS for Perl prior to 4.41. A UTF-8 BOM prefixed input with a throwing decode filter callback can cause the decoder to skip restoration of the input pointer, leaving the scalar with an offset pointer. When the scalar is freed, the allocator may receive an invali...

CVE-2026-9334

Cpanel::JSON::XS (Perl) is affected by a type-confusion issue in decode_hv() for versions before 4.41 when dupkeys_as_arrayref is enabled. The code tests duplicate keys by evaluating SvTYPE (old_value) != SVt_RV && SvTYPE (SvRV (old_value)) != SVt_PVAV, which dereferences a value via SvRV(old_val...
