{"id":"CVE-2026-44974","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-44974","generatedAt":"2026-10-27T23:57:48.270Z","title":"This can allow an upload filename allowlist bypass in headers such as Content-Disposition: form-data; name=\"file\"; filename=\"safe.txt\"; filename=\"shell.php\".","description":"@hapi/content provided HTTP Content-* headers parsing. 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.","published":"2026-07-17T20:17:17.000Z","lastModified":"2026-10-24T20:10:00.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"4.0","score":7.7,"severity":"HIGH","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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-436"],"affected":[],"epss":{"score":0.00472,"percentile":0.40575,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.47%).
