Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

NewCVE-2026-100648 (opens in a new tab)How to fix?
Upgrade vllm to version 0.29.0 or higher.
Overview
vllm is an A high-throughput and memory-efficient inference and serving engine for LLMs
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via load_file in vllm/multimodal/media/audio.py, where the VLLM_MAX_AUDIO_CLIP_FILESIZE_MB file size limit was not enforced on local file:// paths and multimodal chat audio inputs. An authenticated attacker can supply an arbitrarily large audio file through these unguarded paths, causing excessive resource consumption and crashing the service. The fix adds a call to _validate_encoded_size before decoding in load_file, extending the existing size check to all audio input paths.
