Prior to 0.5.2, 9router validates image URLs by resolving the host before fetching, but open-sse/translator/concerns/image.js performs the later server-side image fetch with a separate DNS resolution. An authenticated attacker with access to the LLM proxy can use a vision-capable model and an attacker-controlled DNS name that first resolves to a public IP and then rebinds to an internal address, allowing server-side requests to internal-only HTTP services. This issue is fixed in version 0.5.2.","state":0,"publishedAt":"2026-07-10T15:30:49.514+00:00","modifiedAt":"2026-07-13T18:11:54.297+00:00","affected":[{"ecosystem":"Vendor product","name":"9router","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"decolua\",\n                    \"product\": \"9router\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.5.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:L","score":7.4,"severity":"HIGH"}],"references":["https://github.com/decolua/9router/security/advisories/GHSA-cmhj-wh2f-9cgx","https://github.com/decolua/9router/commit/c7d07448c58bec1200741de0b73305b860416b82","https://github.com/decolua/9router/releases/tag/v0.5.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-56676","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-56676","identifiers":["CVE-2026-56676"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
