HIGH 7.1EPSS 0.45%
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.45%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
SurrealDB before 3.1.0 fails to enforce recursion depth limits in the type/kind parser when processing nested type annotations. Authenticated attackers can send queries with deeply nested type annotations to exhaust server memory and crash the process.
