Cpanel::JSON::XS versions before 4.80 for Perl use the parent interpreter's scalars from a parser object cloned into a new ithread. A parser object holds its callbacks and its incremental parse buffer as raw scalar pointers. When a thread is created, these are copied into the new interpreter...

CVE-2026-110681 Cpanel::JSON::XS versions before 4.80 for Perl use the parent interpreter's scalars from a parser object cloned into a new ithread

CVE-2026-110681

The Cpanel::JSON::XS Perl module, in versions before 4.80 , is vulnerable to a Use After Free (CWE-416) issue. The root cause is that a parser object holds callbacks and incremental parse buffers as raw scalar pointers. When a thread is created, these pointers are copied into the new interpreter ...

CVE-2026-110680 Cpanel::JSON::XS versions from 4.20 before 4.80 for Perl write out of bounds when a tied or shared hash grows during canonical encoding in encode_hv

Cpanel::JSON::XS versions from 4.20 before 4.80 for Perl write out of bounds when a tied or shared hash grows during canonical encoding in encodehv. With canonical, the keys of a tied or threads::shared hash are counted before a second pass collects them for sorting. The encoder uses a fixed...

CVE-2026-110680

Cpanel::JSON::XS versions from 4.20 before 4.80 for Perl write out of bounds when a tied or shared hash grows during canonical encoding in encodehv. With canonical, the keys of a tied or threads::shared hash are counted before a second pass collects them for sorting. The encoder uses a fixed...

CVE-2026-110680

The Cpanel::JSON::XS Perl module, versions 4.20 through 4.79 , is vulnerable to a write out of bounds error during canonical encoding in the encode_hv function. The issue occurs when a tied or threads::shared hash grows between a counting pass and a subsequent collection pass for sorting. Because...

CVE-2026-110678 Cpanel::JSON::XS versions before 4.80 for Perl allow memory exhaustion by buffering incremental input past max_size in incr_parse

Cpanel::JSON::XS versions before 4.80 for Perl allow memory exhaustion by buffering incremental input past maxsize in incrparse. The parser appends each chunk to its buffer. In scalar or list context, it compares maxsize with how far it has progressed, not with the buffer length. A chunk that...

CVE-2026-110678

The Cpanel::JSON::XS Perl module in versions before 4.80 is vulnerable to memory exhaustion due to improper bounds checking in the incr_parse function. The parser appends input chunks to a buffer but incorrectly compares the max_size against the progression progress rather than the actual buffer ...

CVE-2026-110677

The Cpanel::JSON::XS Perl module, versions 4.28 through 4.79 , contains a memory leak vulnerability in the decode_hv function when using the dupkeys_as_arrayref option. When a duplicate object key is encountered, the values are collected into a new array; however, an extra reference is never rele...

CVE-2026-110677 Cpanel::JSON::XS versions from 4.28 before 4.80 for Perl leak the array collecting duplicate key values under dupkeys_as_arrayref in decode_hv

Cpanel::JSON::XS versions from 4.28 before 4.80 for Perl leak the array collecting duplicate key values under dupkeysasarrayref in decodehv. With dupkeysasarrayref, the values of a duplicate object key are collected into a new array. An extra reference is never released, so the array and every...
