Because adminer/include/auth.inc.php invokes Driver::connect() before the login result is validated, an unauthenticated attacker who submits crafted auth[server], auth[username], and auth[password] parameters can cause the Adminer server to issue an HTTP GET request (via get_url()/file_get_contents()) to an arbitrary reachable host and port. The driver validates only general server syntax and does not block loopback, private, link-local, or other reserved addresses; if no port is given it appends the default 9200, and Adminer's generic port check rejects ports below 1024. Selected JSON error fields from non-2xx Elasticsearch-style responses, as well as connection failures, are rendered on the login page, providing a port-scanning oracle and enabling internal network reconnaissance and service fingerprinting. Exploitation requires that the optional Elasticsearch driver be explicitly deployed (e.g., via the adminer/elastic.php template or an adminer_object() configuration; it is not loaded in a default build) and that PHP allow_url_fopen be enabled.","state":0,"publishedAt":"2026-09-26T13:23:53.613+00:00","modifiedAt":"2026-09-28T16:28:42.083+00:00","affected":[{"ecosystem":"Vendor product","name":"adminer","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"vrana\",\n                    \"product\": \"adminer\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"6.0.2\"\n                        },\n                        {\n                            \"version\": \"6.0.2\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\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:L/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:C/C:L/I:N/A:N","score":5.8,"severity":"MEDIUM"}],"references":["https://github.com/vrana/adminer/security/advisories/GHSA-q8h3-4cx4-prgm","https://www.vulncheck.com/advisories/adminer-before-6.0.2-unauthenticated-ssrf-via-elasticsearch-driver"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100696","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100696","identifiers":["CVE-2026-100696"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
