Summary

CVE-2026-102634 is a high-severity Use of Multiple Resources with Duplicate Identifier (CWE-694) vulnerability. Its CVSS base score is 8.7 (High).

Operationally, ranked at the 46th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to IA-4 (Identifier Management) — see the control section below for these in your framework.

Vulnerability Data

SGLang through 0.5.20 in prefill/decode disaggregation mode fails to validate duplicate bootstrap_room fields in /generate requests with Mooncake KV transfer backend. Unauthenticated attackers can send concurrent requests with identical bootstrap_room values to crash scheduler processes or hang other users' requests…

Mitigating Controls (NIST 800-53 r5) AI

IA-4 Identifier Management partial match

Identifier management directly requires authorization and uniqueness controls that stop duplicate resource identifiers from being assigned or used.

ID.AM-02 partial match
prevents

Maintaining software/service inventories requires and enforces unique identifiers to avoid collisions.

ID.AM-08 partial match
prevents

Lifecycle management of assets includes identifier uniqueness as a supporting practice.

PR.AA-01 partial match
prevents

Managing identities and credentials for users/services/hardware directly requires unique identifiers.

A.5.16 Identity management partial match
prevents

A.5.16(e) directly requires avoiding duplicate identities in one domain (the exact condition CWE-694 names), and (a)-(c) further constrain identity issuance to prevent the duplicate-identifier situation from arising; this stops exploitation in the identity-management slice of the weakness but leaves other resource types (non-identity) and cross-domain cases untouched.
