CVE-2026-10130

Summary

QueryWeaver contains an authentication bypass vulnerability that allows unauthenticated attackers to obtain valid session tokens for existing accounts by submitting a signup request with a known victim email address. The signup route unconditionally creates and links a new token to the matching Identity via a Cypher MERGE operation before checking whether the email belongs to an existing account, causing the server to return a valid authenticated session token for the victim's identity without requiring any prior credentials or user interaction.
