SUSE CVE-2026-110674

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...

SUSE 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...

SUSE 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...

SUSE CVE-2026-110686

Cpanel::JSON::XS versions before 4.80 for Perl use freed filter callbacks when a filter removes itself during decoding in decodehv. A decode copies the parser's filterjsonobject and filterjsonsinglekeyobject callbacks without taking references to them. A filter callback that removes the last...
