PostgreSQL管理ツール「pgAdmin 4」のv9.18が4件の脆弱性を修正 — Webserver認証モードでは、pgAdminに到達できる任意のクライアントが管理者を含む任意の利用者になりすませた https://cyber.nexsight.co/articles/2026/09/18/pgadmin4-v9-18-authentication-bypass-cve-2026-86863-2026-09-18/
A single HTTP header can log you into pgAdmin 4 as Administrator no password required (CVSS 9.8). CVE-2026-86863 affects pgAdmin's Webserver authentication mode, which trusts a client-controlled identity header instead of verifying it came from a real proxy. Anyone who can reach the app can authenticate as any username they choose. Affects pgAdmin 4 from 6.2 before 9.18. The fix adds an explicit opt-in, a trusted-proxy check, and a shared secret.
