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.","cvss_v4":null,"cvss_v3":null,"cwes":["CWE-436"],"references":["https://github.com/rurban/Cpanel-JSON-XS/commit/f632d6690d82c14cd2d76d648805325201c52b83.patch","https://metacpan.org/release/RURBAN/Cpanel-JSON-XS-4.80/changes"],"products":[],"source":"nvd","synced_at":"2026-10-21T03:56:58.798400159+00:00"},"epss":{"cve":"CVE-2026-110682","score":0.00171,"percentile":0.06464,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
