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.
