CVE-2026-82402Public exploitNetwork attack vectorHinoki check available

Unauthenticated open redirect via backslash normalization mismatch

Published Oct 14, 2026 · Updated Oct 14, 2026

Open redirect in Gogs before 0.15.0+dev allows remote attackers to send victims to external sites via crafted /redirect links. IsSameSite in internal/urlx/urlx.go validates a normalized target, but getRedirect and other callers place the original value in the Location response, which browsers interpret as a scheme-relative external URL. No account is required for /redirect; victims must follow a crafted link, enabling phishing through an apparently trusted Gogs domain rather than direct server compromise.
