Affected is the function WeightExporter.send_weights_to_remote_instance of the file python/sglang/srt/model_executor/model_runner_components/weight_exporter.py of the component Weight Exporter. Performing a manipulation of the argument group_name results in denial of service. The attack can be initiated remotely. The exploit has been released to the public and may be used for attacks. The pull request to fix this issue awaits acceptance.","state":0,"publishedAt":"2026-10-19T05:45:18.578+00:00","modifiedAt":"2026-10-19T16:36:26.379+00:00","affected":[{"ecosystem":"Vendor product","name":"SGLang","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"sgl-project\",\n                    \"product\": \"SGLang\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0.5.0\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.2\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.3\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.4\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.5\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.6\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.7\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.8\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.9\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.10\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.11\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.12\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.13\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.14\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.15\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.16\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.17\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.18\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.5.19\",\n                            \"status\": \"affected\"\n                        }\n                    ],\n                    \"cpes\": [\n                        \"cpe:2.3:a:sgl-project:sglang:*:*:*:*:*:*:*:*\"\n                    ],\n                    \"modules\": [\n                        \"Weight Exporter\"\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P","score":6.9,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:P/RL:X/RC:C","score":5.3,"severity":"MEDIUM"},{"system":"CVSS 3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:P/RL:X/RC:C","score":5.3,"severity":"MEDIUM"},{"system":"CVSS 2.0","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P/E:POC/RL:ND/RC:C","score":5,"severity":null}],"references":["https://vuldb.com/vuln/421762","https://vuldb.com/vuln/421762/cti","https://vuldb.com/cve/CVE-2026-112083","https://vuldb.com/submit/1009919","https://github.com/sgl-project/sglang/issues/42073","https://github.com/sgl-project/sglang/pull/44314","https://github.com/sgl-project/sglang/"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-112083","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-112083","identifiers":["CVE-2026-112083"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
