When a thread is created, these are copied into the new interpreter unchanged, so the child's parser uses, and later frees, scalars that belong to the parent and may already have been freed there.\n\nA parser created before a thread starts and used inside it can call freed callbacks, corrupt reference counts and crash the process.","cvss_v4":null,"cvss_v3":null,"cwes":["CWE-416"],"references":["https://github.com/rurban/Cpanel-JSON-XS/commit/c53eefbaa59c344abd4c71762118da04280987e8.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-2026-110681","score":0.00171,"percentile":0.06449,"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).
