What is CVE-2026-63757?

SurrealDB versions prior to 3.1.0 are susceptible to a session hijacking issue, where the HTTP /rpc sessions method reveals session UUIDs without requiring authentication. This flaw permits unauthenticated attackers to enumerate session UUIDs and impersonate valid users, compromising data integrity and confidentiality through read, write, and delete operations, while also potentially escalating privileges.

Affected Version(s)

surrealdb 0 < 3.1.0
