{"id":"CVE-2026-110682","summary":"Cpanel::JSON::XS versions from 4.42 before 4.80 for Perl let input chunking change the decoded value of top-level numbers in incr_parse","details":"Cpanel::JSON::XS versions from 4.42 before 4.80 for Perl let input chunking change the decoded value of top-level numbers in incr_parse.\n\nallow_nonref is enabled by default and incr_parse inherits it. A top-level number, true, false or null has no closing delimiter, so the incremental parser decodes whatever has arrived. The bytes 12 decode as one value when read together, but as 1 and then 2 when split across two reads.\n\nA peer that can influence read boundaries can change how many messages a stream consumer decodes and what values they carry.","modified":"2026-10-20T02:44:14.506429005Z","published":"2026-10-19T18:12:09.582Z","database_specific":{"cna_assigner":"CPANSec","cwe_ids":["CWE-436"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110682.json"},"references":[{"type":"WEB","url":"https://cpan.org/modules"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110682.json"},{"type":"PACKAGE","url":"https://github.com/rurban/Cpanel-JSON-XS"},{"type":"FIX","url":"https://github.com/rurban/Cpanel-JSON-XS/commit/f632d6690d82c14cd2d76d648805325201c52b83.patch"},{"type":"ADVISORY","url":"https://metacpan.org/release/RURBAN/Cpanel-JSON-XS-4.80/changes"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110682"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/rurban/cpanel-json-xs","events":[{"introduced":"a4cf44c127f51b3f2bf743009985ffff832dcd7a"},{"fixed":"5552a527abb648d9eb4134e91412800013ddecb9"}],"database_specific":{"extracted_events":[{"introduced":"4.42"},{"fixed":"4.80"}],"source":"AFFECTED_FIELD"}}],"versions":["4.53","4.52","4.51","4.50","4.44","4.43","4.42"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-110682.json"}}],"schema_version":"1.9.0"}
