CVE ID :CVE-2026-12049<\/p>\n

Description :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= — a link typically delivered by phishing — would be sent to an attacker-controlled host directly out of the trusted auth flow.<\/p>\n
The 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.<\/p>\n
Fix 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.<\/p>\n
This issue affects pgAdmin 4: from 6.0 before 9.16.<\/p>\n
Severity: 5.3 | MEDIUM<\/p>\n
