Doc Text:
A flaw was found in vLLM. Remote attackers can exploit this vulnerability by providing a URL to an excessively large media file. The AsyncMediaIO.fetch_audio and AsyncMediaIO.fetch_image functions, responsible for fetching user-supplied media, do not limit the response size. This oversight allows an attacker to exhaust server memory, leading to a Denial of Service (DoS).

Description OSIDB Bzimport 2026-08-28 15:33:12 UTC
vLLM up to and including 0.17.0 allows remote attackers to cause a Denial of Service via memory exhaustion. The AsyncMediaIO.fetch_audio and AsyncMediaIO.fetch_image functions in multimodal/inputs.py fetch user-supplied media URLs using aiohttp and call r.read() without enforcing a maximum response size, allowing an attacker to exhaust server memory by providing a URL to an arbitrarily large file.
