Threats affecting pkg:npm/nuxt-modules/og-image

Nuxt OG Image generates OG Images with Vue templates in Nuxt. From 6.0.2 until 6.7.0, nuxt-og-image exposes the unauthenticated /_og/d/** route when the documented defaults security.strict = false and security.secret = "" are used, and base64url-decodes the fonts parameter through decodeOgImageParams. Attacker-controlled fonts[].path values flow through loadDefinedFonts into the font-assets/node.js binding, which performs a server-side fetch without validating the URL scheme, origin, resolved address, or redirects. This permits blind requests to loopback, private, link-local, cloud metadata, and other internal HTTP services, while differences in the outer response status and timing can reveal service reachability. Slow targets can also occupy OG image render workers for the configured fetch and render timeouts. This issue is fixed in version 6.7.0.

Nuxt OG Image generates OG Images with Vue templates in Nuxt. The isBlockedUrl() denylist introduced in nuxt-og-image@6.2.5 to remediate GHSA-pqhr-mp3f-hrpp (Dmitry Prokhorov / Positive Technologies, March 2026) is incomplete. It has an incomplete IPv6 prefix list and is missing redirect re-validation. This vulnerability is fixed in 6.4.9.

Prior to version 6.2.5, 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. This issue has been patched in version 6.2.5.
