CVE-2026-110682

The Cpanel::JSON::XS Perl module (versions 4.42 before 4.80 ) is vulnerable to an interpretation conflict in its incr_parse function. Because allow_nonref is enabled by default, the incremental parser decodes whatever bytes have arrived for top-level numbers, booleans, or nulls since they lack cl...

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

The Cpanel::JSON::XS Perl module (versions before 4.80 ) is vulnerable to a use-after-free issue. The root cause is that a parser object holds its callbacks and incremental parse buffer as raw scalar pointers . When a thread is created, these pointers are copied into a new ithread interpreter unc...

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

A flaw in perl-Cpanel-JSON-XS versions from 4.20 before 4.80 for Perl allows an out-of-bounds write during canonical encoding in the encode_hv function. When canonical sorting is enabled, the encoder counts the keys of a tied or threads::shared hash in a first pass and allocates either a 64-entry...

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...
