Nuxt OG Image is vulnerable to Denial of Service via unbounded image dimensions

CVE-2026-34404 / GHSA-c7xp-q6q8-hg76

More information

Details

Product: Nuxt OG Image
Version: 6.1.2
CWE-ID: CWE-404: Improper Resource Shutdown or Release
Description: Failure to limit the length and width of the generated image results in a denial of service.
Impact: Denial of service
Exploitation condition: An external user
Mitigation: Implement a limitation on the width and length of the generated image.
Researcher: Dmitry Prokhorov (Positive Technologies)

Research

During the analysis of the nuxt-og-image package, which is shipped with the nuxt-seo package, a zero‑day vulnerability was discovered.
This research revealed that 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.

Listing 1. The content of the configuration file nuxt.config.ts

export default defineNuxtConfig({
  modules: ['nuxt-og-image'],
  devServer: {
    host: 'web-test.local',
    port: 3000
  },
  site: {
    url: 'http://web-test.local:3000',
  },
  ogImage: {
    fonts: [
      'Inter:400', 
      'Inter:700'
    ],
  }
})

Vulnerability reproduction

To demonstrate the proof‑of‑concept, a request should be sent with the increased width and height parameters. This will cause a delay and exhaust the server’s resources during image generation.

Listing 2. HTTP-request example

GET /_og/d/og.png?width=20000&height=20000 HTTP/1.1
Host: web-test.local:3000

Figure 1. HTTP-response: denial-of-service error

After sending a HTTP-request, the test server's memory was exhausted.

Nuxt OG Image vulnerable to Server-Side Request Forgery via user-controlled parameters

GHSA-pqhr-mp3f-hrpp

More information

Details

Product: Nuxt OG Image
Version: < 6.2.5
CWE-ID: CWE-918: Server-Side Request Forgery

Description

The image generation endpoint (/_og/d/) accepts user-controlled parameters that are passed to the server-side renderer without proper validation or filtering. An attacker can trigger server-side requests to internal network addresses through multiple vectors.

Impact

Scanning internal ports and services inaccessible from the outside
Reading sensitive data from cloud infrastructure metadata services (tokens, credentials) when verbose error output is enabled

Attack Vectors

Three distinct vectors were identified, all exploiting the same underlying lack of URL validation:

Vector 1: CSS `background-image` injection via `style` parameter

GET /_og/d/og.png?style=background-image:+url('http://127.0.0.1:8888/secret')

Vector 2: `<img src>` injection via `html` parameter

GET /_og/d/og.png?html=<img src="http://127.0.0.1:8888/secret">

When verbose errors are enabled, the response content is leaked in base64-encoded error messages.

Vector 3: SVG `<image href>` injection via `html` parameter

GET /_og/d/og.png?html=<svg><image href="http://127.0.0.1:8888/secret"></svg>

Mitigation

Fixed in v6.2.5. The image source plugin now blocks requests to private IP ranges (IPv4/IPv6), loopback addresses, link-local addresses, and cloud metadata endpoints. Decimal/hexadecimal IP encoding bypasses are also handled.

Nuxt OG Image is vulnerable to reflected XSS via query parameter injection into HTML attributes

CVE-2026-34405 / GHSA-mg36-wvcr-m75h

More information

Details

Product: Nuxt OG Image
Version: 6.1.2
CWE-ID: CWE-79: Improper Neutralization of Input During Web Page Generation
Description: Incorrect parsing of GET parameters leads to the possibility of HTML injection and JavaScript code injection.
Impact: Client-Side JavaScript Execution
Exploitation condition: An external user
Mitigation: Correct the logic of parsing GET parameters and their subsequent implementation into the generated page.
Researcher: Dmitry Prokhorov (Positive Technologies)

Research

During the analysis of the nuxt-og-image package, which is shipped with the nuxt-seo package, a zero‑day vulnerability was discovered.
This research revealed that the image‑generation component by the URI: /_og/d/ (and, in older versions, /og-image/) contains a vulnerability that allows injection of arbitrary attributes into the HTML page body. The vulnerability was reproduced using the standard configuration and the default templates.

Listing 1. The content of the configuration file nuxt.config.ts

export default defineNuxtConfig({
  modules: ['nuxt-og-image'],
  devServer: {
    host: 'web-test.local',
    port: 3000
  },
  site: {
    url: 'http://web-test.local:3000',
  },
  ogImage: {
    fonts: [
      'Inter:400', 
      'Inter:700'
    ],
  }
})

Vulnerability reproduction

To demonstrate the proof‑of‑concept, follow the URI: /_og/d/og.html?width=1000&height=1000&onmouseover=alert(document.cookie)&autofocus
The injected parameters onmouseover=alert(document.cookie) and autofocus are treated as attributes and are inserted directly into the generated HTML page.

Listing 2. HTTP-request example

GET /_og/d/og.html?width=1000&height=1000&onmouseover=alert(document.cookie) HTTP/1.1
Host: web-test.local:3000
