Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Scriban (NuGet packages scriban and Scriban.Signed) versions before 6.6.0 are vulnerable. When an object containing a circular reference is rendered, the default unlimited ObjectRecursionLimit lets the renderer recurse until the stack overflows, crashing the hosting process. An attacker who can influence the data passed to the renderer, such as a cyclic object graph from user-supplied input, can cause a denial of service. Upgrade to version 6.6.0 or later.
