What is CVE-2026-102527?
CVE-2026-102527 is a medium-severity vulnerability in nuxt-modules og-image, published on 15 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Nuxt OG Image generates OG Images with Vue templates in Nuxt. From 6.2.5 until 6.7.0, the dynamic /_og/d/*.png route accepts unsigned requests while resolvePathCacheKey() produces cache keys from the request path, site URL, and normalized rendering options exposed through image URLs and server responses. An unauthenticated attacker can provide attacker-controlled image data through the title parameter together with a derived cacheKey and populate the cache slot used for a legitimate Open Graph image, causing spoofed image content to be served to users. This issue is fixed in version 6.7.0.
Weakness: CWE-349
