CVE-2026-55514

A flaw was found in vLLM, a library for Large Language Model LLM inference and serving. A remote attacker, authorized to make a /v1/completions request, can send a specially crafted prompt embeds payload. This action causes the EngineCore to fail an assertion and fatally crash, leading to a Denia...
