CVE-2026-34404
Nuxt OG Image is vulnerable to Denial of Service via unbounded image dimensions
Impact
Nuxt OG Image generates OG Images with Vue templates in Nuxt. Prior to version 6.2.5, the image‑generation component by the URI: /_og/d/ (and, in older versions, /og-image/) contains a Denial of Service (DoS) vulnerability. The issue arises because there is no restriction on the width and height parameters of the generated image. The vulnerability was reproduced using the standard configuration and the default templates. This issue has been patched in version 6.2.5.
