CVE-2025-48370Network attack vector

Unintended API operations via malformed UUID path segments

Published May 27, 2025 · Updated Jul 27, 2026

Path traversal in Supabase Auth JS before 2.70.0 allows remote attackers to invoke an unintended Auth API route using malformed identifiers. GoTrueAdminApi interpolates userId and factorId directly into admin request paths without first enforcing UUID syntax, allowing path separators to alter route resolution. Exposure requires a consuming application to pass remote input into these server-only methods without validation; affected calls can reach the wrong API operation.
