CVE-2026-105760: vLLM resource exhaustion in GLMGA video backend

CVE-2026-105760 · Severity: medium · CVSS 5.3 · Published 2026-10-05

vLLM is an open-source inference engine for large language models that processes video input through a GLMGA backend. An attacker can submit requests with large video frame sampling parameters that cause excessive CPU and memory consumption in the shared media-loading executor, potentially disrupting service availability for other users.

Technologies: vllm (PyPI), vLLM Project vllm. Vendors: PyPI, vLLM Project.

Quick answers

Which products and versions are affected?
vllm (PyPI) >= 0.23.0rc2, < 0.30.0, ECOSYSTEM:introduced=0.23.0rc2,fixed=0.30.0; vLLM Project vllm prior to 0.30.0.
Is there a fix for CVE-2026-105760?
Yes. vllm (PyPI): upgrade to 0.30.0 or later. Junglewise finds every place you run it, drafts the upgrade and applies it once you approve.
How is CVE-2026-105760 attacked?
It is attacked over the network, in a software library.
Am I affected by CVE-2026-105760?
Check whether you run vllm (PyPI) or vLLM Project vllm at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

How to fix

  • vllm (PyPI): upgrade to 0.30.0 or later
    pip install "vllm>=0.30.0"

Technical details

A request-level resource exhaustion vulnerability in vLLM's GLMGA video backend allows attackers to supply large fps and max_frames values via media_io_kwargs without strict resource limits. The GLMGA backend constructs a deduplicated frame-index list based on attacker input, enabling a small valid video to trigger disproportionate CPU and memory consumption in the shared media-loading executor. This is a network-accessible DoS vector in multi-tenant or shared inference scenarios.
