In scalar or list context, it compares max_size with how far it has progressed, not with the buffer length. A chunk that starts with a NUL byte stops the parser before it progresses, and a call in void context skips the check, so the buffer grows without limit.\n\nA peer streaming data to an incr_parse consumer can exhaust process memory regardless of max_size.","state":0,"publishedAt":"2026-10-19T18:11:58.61+00:00","modifiedAt":"2026-10-19T18:11:58.61+00:00","affected":[{"ecosystem":"https://cpan.org/modules","name":"Cpanel-JSON-XS","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"collectionURL\": \"https://cpan.org/modules\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"modules\": [\n                        \"Cpanel::JSON::XS\"\n                    ],\n                    \"packageName\": \"Cpanel-JSON-XS\",\n                    \"packageURL\": \"pkg:cpan/Cpanel-JSON-XS\",\n                    \"programFiles\": [\n                        \"XS.xs\"\n                    ],\n                    \"programRoutines\": [\n                        {\n                            \"name\": \"Cpanel::JSON::XS::incr_parse\"\n                        }\n                    ],\n                    \"repo\": \"https://github.com/rurban/Cpanel-JSON-XS\",\n                    \"versions\": [\n                        {\n                            \"lessThan\": \"4.80\",\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"custom\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://github.com/rurban/Cpanel-JSON-XS/commit/d516f296b1714e06b0fb9eaae72f4558ae3d83d6.patch","https://metacpan.org/release/RURBAN/Cpanel-JSON-XS-4.80/changes"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-110678","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-110678","identifiers":["CVE-2026-110678"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
