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.","cvss_v4":null,"cvss_v3":null,"cwes":["CWE-770"],"references":["https://github.com/rurban/Cpanel-JSON-XS/commit/d516f296b1714e06b0fb9eaae72f4558ae3d83d6.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-2026-110678","score":0.00171,"percentile":0.06463,"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).
