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":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD 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":null}],"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://euvd.enisa.europa.eu/vulnerability/EUVD-2026-42929","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Jul 10, 2026, 3:30:49 PM","dateUpdated":"Jul 13, 2026, 6:11:54 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
