Vulnerability details
The vulnerability allows a remote attacker with low privileges to cause cross-request substitution of cached processed images in vLLM.
The vulnerability exists due to the multimodal processor cache using a caller-controlled UUID in EXIF ImageID metadata as image identity without binding it to image content or the requesting principal. A remote attacker with low privileges can submit different images carrying the same UUID so later requests receive the first image's cached processed media.
