It is important to note that because this debug function was only used in tests and demos, it was not exploitable in a normal environment.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-125"],"references":["https://github.com/cloudflare/lua-resty-json/pull/14","https://github.com/cloudflare/lua-resty-json/security/advisories/GHSA-h8rp-9622-83pg","https://github.com/cloudflare/lua-resty-json/pull/14","https://github.com/cloudflare/lua-resty-json/security/advisories/GHSA-h8rp-9622-83pg"],"products":["cloudflare:lua-resty-json"],"source":"nvd","synced_at":"2026-10-19T21:38:24.161619714+00:00"},"epss":{"cve":"CVE-2023-3040","score":0.0071,"percentile":0.53532,"date":"2026-10-31"},"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).
