`CVE:CVE-2026-25048`	vulnerable	2026-06-08 07:53:18.888688	xgrammar: Multi-layer nesting causes DoS xgrammar is an open-source library for efficient, flexible, and portable structured generation. Prior to version 0.1.32, the multi-level nested syntax caused a segmentation fault (core dumped). This issue has been patched in version 0.1.32.

`CVE:CVE-2025-58446`	vulnerable	2026-06-08 07:35:18.293320	xgrammar vulnerable to denial of service by huge enum grammar xgrammar is an open-source library for efficient, flexible, and portable structured generation. A grammar optimizer introduced in 0.1.23 processes large grammars (>100k characters) at very low rates, and can be used for DOS of model providers. This issue is fixed in version 0.1.24.

`CVE:CVE-2025-57809`	vulnerable	2026-06-08 07:33:16.161522	XGrammar affected by Denial of Service by infinite recursion grammars XGrammar is an open-source library for efficient, flexible, and portable structured generation. Prior to version 0.1.21, XGrammar has an infinite recursion issue in the grammar. This issue has been resolved in version 0.1.21.

`CVE:CVE-2025-32381`	vulnerable	2026-06-08 07:18:59.698384	Denial of Service by abusing xgrammar unbounded cache in memory MEDIUM (6.5) XGrammar is an open-source library for efficient, flexible, and portable structured generation. Prior to 0.1.18, Xgrammar includes a cache for compiled grammars to increase performance with repeated use of the same grammar. This cache is held in memory. Since the cache is unbounded, a system making use of xgrammar can be abused to fill up a host's memory and case a denial of service. For example, sending many small requests to an LLM inference server with unique JSON schemas would eventually cause this denial of service to occur. This vulnerability is fixed in 0.1.18.
