CVE-2026-93088 (GCVE-0-2026-93088)

Vulnerability from cvelistv5 – Published: 2026-09-22 14:07 – Updated: 2026-09-22 18:45

Title

CVE-2026-93088

Summary

SGLang's multimodal generation runtime is vulnerable to unauthenticated arbitrary code execution because the disaggregated-diffusion orchestrator's DiffusionServer binds an unauthenticated ZeroMQ ROUTER socket to a network interface and passes the final frame of received multipart messages directly to pickle.loads() before any validation occurs.

Severity

9.8 (Critical)

CVE-2026-93688 (GCVE-0-2026-93688)

Vulnerability from cvelistv5 – Published: 2026-09-18 15:06 – Updated: 2026-09-21 20:51

Title

SGLang through 0.5.19 Unbounded Memory Allocation via bootstrap_room

Summary

SGLang through 0.5.19 in prefill/decode disaggregation mode with Mooncake KV transfer backend fails to validate bootstrap_room values, allowing unbounded transfer state allocation. Unauthenticated attackers can reach the decode engine's POST /generate endpoint and submit arbitrary bootstrap_room values to exhaust prefill process memory until out-of-memory termination.

CVE-2026-93838 (GCVE-0-2026-93838)

Vulnerability from cvelistv5 – Published: 2026-09-18 19:06 – Updated: 2026-09-24 14:23

Title

SGLang through 0.5.20 Unbounded Memory Allocation via STAGING_REQ chunk_idx

Summary

SGLang versions through 0.5.20 contain an unbounded memory allocation vulnerability in handle_staging_req() that fails to validate chunk_idx from ZMQ STAGING_REQ frames in prefill/decode disaggregation deployments. Attackers with access to the decode engine's internal ZMQ rank port can send a frame with an extremely large chunk_idx value, causing the scheduler to allocate memory until the system runs out and terminates the process.
