Summary

vLLM before 0.32.0 passes attacker-controlled image bytes to Pillow without restricting the decoder, so the MIME label does not limit the parsed format (CWE-20). An unauthenticated remote attacker can send an EPS payload through image request paths such as parse_image() that reach host components. A host with a vulnerable Ghostscript lets the payload run commands with vLLM's privileges, and Pillow 12.0.0 through 12.2.0 lets it exhaust media-loading workers.

Description from the CNA

vLLM is an inference and serving engine for large language models. Prior to 0.32.0, ImageMediaIO passes attacker-controlled image bytes to Pillow through Image.open(BytesIO(data)) without restricting decoder selection, and the MIME label does not constrain the selected format. Image-capable request paths through parse_image() and fetch_image() can therefore dispatch an EPS payload to host components. A host with Ghostscript affected by CVE-2024-29510 can execute commands with the vLLM process's privileges, while environments using Pillow 12.0.0 through 12.2.0 can trigger CVE-2026-59203 and exhaust media-loading workers. Deployments without the applicable vulnerable dependency are not affected by that corresponding impact. This issue is fixed in version 0.32.0.

Remediation

Upgrade vllm to 0.32.0, which fixes all earlier versions. Red Hat AI Inference Server 3.5 is fixed by RHSA-2026:94702 (CPU), RHSA-2026:94709 (ROCm), RHSA-2026:94717 (Spyre), RHSA-2026:94721 (Gaudi Tech Preview) and RHSA-2026:94738 (CUDA). Red Hat has no fix plan for Red Hat Enterprise Linux AI (RHEL AI) 3, Red Hat OpenShift AI (RHOAI) or other Red Hat AI Inference Server versions.
