"CVE-2026-7120"
],
"details": "### Impact\n\n`@fastify/static` evaluates the `allowedPath` callback before normalizing dot segments and duplicate slashes in the pathname used for file resolution. Non-canonical pathnames such as `//file`, `/./file`, or `/public/../private/file` bypass `allowedPath` filtering while resolving to the intended file on disk.\n\nApplications that use `allowedPath` as a security boundary to restrict access to specific static files or path subtrees may unintentionally expose files that were intended to be denied.\n\n### Patches\n\nUpgrade to `@fastify/static` >= 10.1.2.\n\n### Workarounds\n\nNone. Upgrade to the patched version.",
