When using automatic content decoding an attacker can craft a request body that can make the server crash with the following request: `curl -d \"array[_0][0][array][_0][0][array]$(for f in $(seq 1100); do echo -n '[_0][0][array]'; done)[string][_0]=hello%20world\" http://localhost:8080/foo`. The issue is unbounded, attacker controlled stack growth which will at some point lead to a stack overflow and a process crash. This issue has been fixed in version 4.61.1.","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-674","CWE-120"],"references":["https://github.com/vapor/vapor/commit/6c63226a4ab82ce53730eb1afb9ca63866fcf033","https://github.com/vapor/vapor/security/advisories/GHSA-qvxg-wjxc-r4gg","https://github.com/vapor/vapor/commit/6c63226a4ab82ce53730eb1afb9ca63866fcf033","https://github.com/vapor/vapor/security/advisories/GHSA-qvxg-wjxc-r4gg"],"products":["vapor:vapor"],"source":"nvd","synced_at":"2026-10-19T21:32:39.174919249+00:00"},"epss":{"cve":"CVE-2022-31019","score":0.01663,"percentile":0.76705,"date":"2026-11-01"},"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).
