CVE-2026-116177

vLLM 0.10.2 before 0.25.0 DoS via Nemotron-VL Processor Decompression-Bomb Guard Bypass

Published Oct 25, 2026 CVSS 4.0 · 8.7 High EPSS < 1% KEV · Not listed

Description

vLLM from 0.10.2 before 0.25.0 contains an uncontrolled resource consumption vulnerability that allows unauthenticated attackers to exhaust memory because the Nemotron-VL processors globally set Image.MAX_IMAGE_PIXELS to None. Attackers can submit a pathological decompression-bomb image to /v1/chat/completions to OOM-kill the worker and deny service to co-tenants.

Analysis

Technical impact

vLLM versions 0.10.2 through 0.24.9 contain an uncontrolled resource consumption flaw that allows attackers to submit a pathological decompression‑bomb image to the /v1/chat/completions endpoint, causing the worker process to exhaust memory, be OOM‑killed, and deny service to other tenants. The flaw arises because the Nemotron‑VL processors globally set Image.MAX_IMAGE_PIXELS to None, removing the built‑in protection against oversized images. This attack can be performed without authentication, providing a straightforward path to disrupt the system.

Affected Systems

The vulnerability affects the vllm-project vLLM product. All releases starting with 0.10.2 and prior to 0.25.0 are impacted. If you are running any of those versions, the application is susceptible to the described denial‑of‑service attack.

Risk and Exploitability

The CVSS score of 8.7 classifies this as a high‑impact vulnerability. The EPSS score is not available, and the CVE is not listed in CISA’s KEV catalog. The flaw can be exploited remotely by sending a single oversized image request over HTTP, and no authentication is required. Because the conditions are minimal and the effect can be catastrophic for shared deployments, the risk to operational availability is significant.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

Upgrade vLLM to version 0.25.0 or later, where the Nemotron‑VL image guard is correctly enforced.
If an upgrade is not immediately possible, configure the image processing component to impose a hard limit on maximum pixels or reject oversized images before delegation to the Nemotron‑VL processors.
Implement request size limits or a web application firewall rule to block requests with extremely large image payloads and monitor worker memory usage for abnormal spikes.
