AZL-109866 CVE-2026-110680 affecting package perl-Cpanel-JSON-XS 4.39-1

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-2026-110677

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...

CVE-2026-110684

Cpanel::JSON::XS versions from 3.0202 before 4.80 for Perl leak memory and retain overloaded objects when encoding values as strings in encodestringify. encodestringify writes a value in its string form under allowstringify, under convertblessed for objects without TOJSON, and under allowbignum...

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-2026-110682

Cpanel::JSON::XS versions from 4.42 before 4.80 for Perl let input chunking change the decoded value of top-level numbers in incrparse. allownonref is enabled by default and incrparse inherits it. A top-level number, true, false or null has no closing delimiter, so the incremental parser decodes...

DEBIAN-CVE-2026-110678

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...

DEBIAN-CVE-2026-110675

Cpanel::JSON::XS versions from 4.33 before 4.80 for Perl accept malformed UTF-8 in bare hash keys under allowbarekey in decodehv. With utf8 and allowbarekey, which relaxed enables, a quoted key is validated as UTF-8 but a bare key's bytes are stored as a UTF-8 flagged string without any check...

AZL-109845 CVE-2026-110676 affecting package perl-Cpanel-JSON-XS 4.39-1

Cpanel::JSON::XS versions before 4.80 for Perl allow memory exhaustion by encoding exponent notation as full decimal digits under allowbignum. With allowbignum, a JSON number with a fraction or exponent decodes to a Math::BigFloat, which stores the exponent separately and so decodes cheaply...

AZL-109836 CVE-2026-110674 affecting package perl-Cpanel-JSON-XS 4.39-1

Cpanel::JSON::XS versions from 4.33 before 4.80 for Perl miss duplicate non-ASCII bare keys, allowing type confusion under dupkeysasarrayref in decodehv. With allowbarekey, which relaxed enables, a bare key containing a non-ASCII byte is stored as UTF-8 but looked up as raw bytes, so a repeated k...

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. 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...
