Vulnerability from github – Published: 2026-09-29 21:33 – Updated: 2026-09-29 21:33

Details

SurrealDB before 3.3.0 contains an authorization bypass in HTTP session construction where check_auth() verifies credentials against Surreal-Auth-NS and Surreal-Auth-DB headers but constructs sessions using Surreal-NS and Surreal-DB headers without validating access permissions. Attackers can authenticate as a user from one tenant while selecting another tenant's namespace and database to read, create, and modify records across tenant boundaries.

Severity
