Attackers can submit arbitrary email addresses and distinguish registered accounts, which return 200 OK, from unregistered accounts, which trigger a 500 Internal Server Error with backend error details, enabling targeted phishing or credential attacks.","state":0,"publishedAt":"2026-10-02T20:17:20.012+00:00","modifiedAt":"2026-10-06T16:41:53.278+00:00","affected":[{"ecosystem":"Vendor product","name":"UTMStack","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"UTMStack\",\n                    \"product\": \"UTMStack\",\n                    \"packageURL\": \"pkg:github/utmstack/UTMStack\",\n                    \"repo\": \"https://github.com/utmstack/UTMStack\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"11.2.16\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":6.9,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/UTMStack/UTMStack/releases/tag/v11.2.16","https://github.com/utmstack/UTMStack/commit/4e7a727c3b8d8e2ad020d3b4f982a6d085dbecdd","https://www.vulncheck.com/advisories/utmstack-account-enumeration-via-password-reset-endpoint"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-82043","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-82043","identifiers":["CVE-2026-82043"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
