An attacker needs to send the victim a crafted file which needs to be opened; this triggers the integer underflow vulnerability (when the file is parsed), leading to elevation of privilege.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-191"],"references":["https://github.com/Tencent/rapidjson/pull/1261/commits/8269bc2bc289e9d343bae51cdf6d23ef0950e001","https://github.com/fmalita/rapidjson/commit/8269bc2bc289e9d343bae51cdf6d23ef0950e001","https://msrc.microsoft.com/update-guide/vulnerability/CVE-2024-38517","https://github.com/Tencent/rapidjson/pull/1261/commits/8269bc2bc289e9d343bae51cdf6d23ef0950e001","https://github.com/fmalita/rapidjson/commit/8269bc2bc289e9d343bae51cdf6d23ef0950e001"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:52:42.518321223+00:00"},"epss":{"cve":"CVE-2024-38517","score":0.00375,"percentile":0.31471,"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).
