CVE-2026-7302 Details
Description
SGLangs multimodal generation runtime is vulnerable to an unauthenticated path traversal vulnerability, allowing an attacker to write arbitrary files anywhere the server process has write access, by including ../ sequences in the upload filename when sent to specific endpoints.
A path traversal vulnerability allowing unauthenticated attackers to write arbitrary files has been identified in SGLang's multimodal generation runtime, versions 0.5.5 and later. The vulnerability arises from the runtime's file upload handling on OpenAI-compatible image and video editing endpoints. The issue allows attackers to exploit the upload filename by including '../' sequences to traverse out of the designated uploads directory and into any location where the server process has write permissions.
