    Reusing a Nonce, Key Pair in Encryption

    astro is an Astro is a modern site builder with web best practices, performance, and DX front-of-mind.

    Affected versions of this package are vulnerable to Reusing a Nonce, Key Pair in Encryption of server island parameters. An attacker can inject malicious HTML or script content into a component by replaying encrypted values between props and slots across different components.

    Note: This is only exploitable if the application uses server islands, two different server island components share the same key name for a prop and a slot, and an attacker has full control over the value of the overlapping prop in a dynamically rendered page.

    Allocation of Resources Without Limits or Throttling

    astro is an Astro is a modern site builder with web best practices, performance, and DX front-of-mind.

    Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the /_server-islands/[name] route handler, which buffers and parses the entire request body as JSON without enforcing a size limit. An attacker can cause the server process to exhaust available memory and crash by sending a single unauthenticated request with a crafted payload containing many small JSON objects, resulting in significant memory amplification.

    How to fix Allocation of Resources Without Limits or Throttling?

    Upgrade astro to version 6.0.0-beta.20 or higher.

    <6.0.0-beta.20
