VLLM (>= 0.12.0, < 0.24.0)

A denial of service vulnerability, CVE-2026-55514, exists in vLLM versions from 0.12.0 up to, but not including, 0.24.0, allowing an authorized remote user to send a specially crafted `/v1/completions` request that leverages pure prompt embeds with an M-RoPE-enabled model to trigger an assertion failure, causing the vLLM server application to fatally crash.
