A vulnerability was identified in sgl-project SGLang up to 0.5.19. This impacts the function Scheduler.expert_distribution_handle of the file python/sglang/srt/eplb/expert_distribution.py of the component Expert-Distribution Recording Endpoint. Such manipulation leads to denial of service. It is possible to launch the attack remotely. The exploit is publicly available and might be used. The pull request to fix this issue awaits acceptance.
A denial-of-service vulnerability exists in SGL Project SGLang versions through 0.5.19. The issue arises in the Expert-Distribution Recording Endpoint, specifically within the Scheduler.expert_distribution_handle function. When the server is not running in expert distribution recorder mode, requests to certain expert distribution record routes cause an uncaught exception that terminates the scheduler process, leading to a complete server shutdown. This vulnerability can be exploited remotely, and the available public exploit takes advantage of the absence of a required API key.
Users can update to SGLang version 0.5.22, where this issue has been fixed.
