CVE-2026-25477Public exploitNetwork attack vector

Phishing redirects via suffix-matching domain regex

Published Mar 2, 2026 · Updated Mar 2, 2026

Open redirect in AFFiNE 0.25.7 and earlier allows remote attackers to send users to malicious sites through redirect-proxy. The redirect-proxy page builds a regular expression from trusted-domain strings without escaping dots or enforcing a domain-label boundary, then assigns a suffix-matching redirect_uri to location.href. No authentication is required, but a user must open a crafted AFFiNE link; the resulting redirect can support credential-phishing pages.
