Summary

In Nuxt OG Image prior to version 6.2.5, the lack of restrictions on width and height parameters in the URI /_og/d/ (and /og-image/) allows a DoS attack by generating oversized images.

Risk Assessment

An attacker can overload the server by generating very large images, potentially leading to denial of service for other users.

Recommendation

Update Nuxt OG Image to version 6.2.5 or later.

Other vulnerabilities in Nuxt OG Image

CVE-2026-34405Medium
Nuxt OG Image before version 6.2.5 has a vulnerability in the image-generation component via URI /_og/d/ (and /og-image/ in older versions) that allows injection of arbitrary attributes into the HTML page body. A fix is available in version 6.2.5.

Original NVD description (English source)

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.
