Prior to 6.0.2, Content.disposition() retained the last occurrence of each duplicate parameter while Content.type() retained the first occurrence of duplicate charset and boundary parameters, creating a parameter-smuggling primitive when another component in the request-processing chain resolves duplicates the opposite way. This can allow an upload filename allowlist bypass in headers such as Content-Disposition: form-data; name=\"file\"; filename=\"safe.txt\"; filename=\"shell.php\". This issue is fixed in version 6.0.2.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:H/SA:N","score":7.7},"cvss_v3":null,"cwes":["CWE-436"],"references":["https://github.com/hapijs/content/commit/3850079550c191d25e3643dc82a6d61144db8c2f","https://github.com/hapijs/content/security/advisories/GHSA-36hh-x5p5-jgc8"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:08.599881581+00:00"},"epss":{"cve":"CVE-2026-44974","score":0.00472,"percentile":0.40556,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-36hh-x5p5-jgc8","url":"https://osv.dev/vulnerability/GHSA-36hh-x5p5-jgc8","summary":"@hapi/content header parser has a parameter smuggling issue that allows upload-filter bypass via duplicate parameters","modified":"2026-09-10T03:51:04.335368532Z","packages":[{"ecosystem":"npm","name":"@hapi/content","purl":"pkg:npm/%40hapi/content","ranges":["<6.0.2"],"fixed":["6.0.2"]}]}],"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).
