"value": "Open redirect in pgAdmin 4's multi-factor authentication flow. The MFA validate and register endpoints honoured the user-supplied 'next' query/form parameter without confirming the target pointed back inside pgAdmin, so an authenticated victim who clicked /mfa/validate?next=<external> -- a link typically delivered by phishing -- would be sent to an attacker-controlled host directly out of the trusted auth flow.\n\nThe defect is a trusted-domain redirect, not a privilege bypass: the attacker gains no read/write access to pgAdmin or the victim's database, but the redirect launders the attacker's destination through pgAdmin's URL, which raises the success rate of credential-phishing follow-on against the victim.\n\nFix introduces a same-origin _is_safe_redirect_url helper and gates every MFA redirect that consumes user-supplied 'next' values through it. The helper allows only relative paths and absolute URLs whose scheme is http(s) and whose host matches the current request host; it rejects external hosts in absolute and protocol-relative form, non-http schemes (javascript:, data:, mailto:), userinfo tricks (http://localhost@attacker/), and backslash variants that some browsers normalize to forward slashes. Unsafe targets fall back to the internal browser index. A dedicated regression test exercises each accept/reject category and the original reporter PoC.\n\nThis issue affects pgAdmin 4: from 6.0 before 9.16."

"value": "Attacker delivers a crafted /mfa/validate?next=<external> URL to a logged-in pgAdmin user (typically via phishing). The endpoint requires login_required so the victim must already be authenticated to pgAdmin -- but the *attacker* needs no pgAdmin privileges at all to construct and deliver the link (PR:N). UI:R captures the click. Scope is unchanged: the defect does not grant the attacker access to pgAdmin's authority or the victim's database session; it only launders the attacker's destination through pgAdmin's URL, which raises credential-phishing success rates. C:N and A:N follow from the same reasoning; I:L acknowledges the integrity impact of an authenticated-flow redirect that lends pgAdmin's trust to an attacker domain.\n\nReviewer note (Dave Page, 2026-06-11): defensible at 4.3 for a token-free open redirect. Heads-up that NVD house style for open redirects often lands at S:C/C:L/I:L -> 6.1, so expect a possible upward rescore by the NVD analyst."
