{"id":"CVE-2026-82042","state":"PUBLISHED","title":"UTMStack < 11.2.16 Authentication Bypass via InternalApiKeyFilter","description":"UTMStack before 11.2.16 contains an authentication bypass vulnerability that allows remote attackers to gain full administrative API access by presenting a valid Utm-Internal-Key header matching the INTERNAL_KEY environment variable value, which the InternalApiKeyFilter accepts for any endpoint without path restriction, constant-time comparison, rate limiting, or audit logging. Attackers who obtain the key value can authenticate without a user account or JWT to create accounts, manage users, exfiltrate data, and modify security rules.","publishedAt":"2026-10-02T20:15:27.035Z","updatedAt":"2026-10-05T14:51:54.025Z","severity":{"score":9.3,"label":"Critical","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["UTMStack UTMStack"],"affected":[{"vendor":"UTMStack","product":"UTMStack","packageURL":"pkg:github/utmstack/UTMStack","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"11.2.16","versionType":"semver"}],"repo":"https://github.com/utmstack/UTMStack"}],"references":["https://github.com/UTMStack/UTMStack/releases/tag/v11.2.16","https://github.com/utmstack/UTMStack/commit/4e7a727c3b8d8e2ad020d3b4f982a6d085dbecdd","https://www.vulncheck.com/advisories/utmstack-authentication-bypass-via-internalapikeyfilter"],"weaknesses":["CWE-306"],"ingestedAt":"2026-10-29T20:13:15.269Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/82xxx/CVE-2026-82042.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-82042","state":"PUBLISHED","datePublished":"2026-10-02T20:15:27.035Z","dateUpdated":"2026-10-05T14:51:54.025Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-08-27T21:39:20.461Z"},"containers":{"cna":{"title":"UTMStack < 11.2.16 Authentication Bypass via InternalApiKeyFilter","descriptions":[{"lang":"en","value":"UTMStack before 11.2.16 contains an authentication bypass vulnerability that allows remote attackers to gain full administrative API access by presenting a valid Utm-Internal-Key header matching the INTERNAL_KEY environment variable value, which the InternalApiKeyFilter accepts for any endpoint without path restriction, constant-time comparison, rate limiting, or audit logging.
