Description

This security bulletin contains information about 1 vulnerability.


1) Resource exhaustion (CVE-ID: N/A)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 5.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in the /v1/completions/derender and /v1/chat/completions/derender endpoints when decoding caller-supplied GenerateResponse token IDs without output bounds. A remote user can send a specially crafted derender request with oversized nested token_id lists to cause a denial of service.

In disaggregated deployments, the issue affects the CPU-only render frontend; when the render router is attached alongside generation, it affects the same OpenAI-compatible server process handling normal client traffic.
