AI-Generated

SurrealDB versions prior to 3.1.0 are vulnerable to a time-of-check/time-of-use race condition in the HTTP /rpc endpoint, enabling unauthenticated attackers to exploit concurrent requests and inherit authenticated session states. This flaw allows attackers to perform operations with the privileges of legitimate users, posing a significant risk to data integrity and confidentiality. Organizations using affected versions should prioritize patching to mitigate the potential for unauthorized access and privilege escalation.

Original NVD Description

SurrealDB versions before 3.1.0 contain a time-of-check/time-of-use race condition in the HTTP /rpc endpoint that allows unauthenticated requests to inherit authenticated session state. Unauthenticated attackers can send concurrent requests to the /rpc endpoint while legitimate authenticated traffic is active to execute operations with hijacked user privileges.
