Overview
xgrammar is an Efficient, Flexible and Portable Structured Generation
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in thread_safe_cache.h, which can be populated by an indefinitely large number of entries corresponding to each new schema encountered. A user can exhaust all available memory on the system running the target application.
Note: A common use case for this caching is vLLM's guided encoding functionality.
