    Interpretation Conflict

    fastify is an overhead web framework, for Node.js.

    Affected versions of this package are vulnerable to Interpretation Conflict via the Content-Type header processing. An attacker can bypass body validation by appending a tab character (\t) and arbitrary content to the Content-Type header, causing the server to treat the body as the intended type without enforcing validation rules.

    Note: This vulnerability affects all Fastify users who rely on Content-Type-based body validation schemas to enforce data integrity or security constraints.

    How to fix Interpretation Conflict?

    Upgrade fastify to version 5.7.2 or higher.

    <5.7.2

    Allocation of Resources Without Limits or Throttling

    fastify is an overhead web framework, for Node.js.

    Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the sendWebStream function. An attacker can cause excessive memory consumption by sending a slow or non-reading client request, leading to unbounded buffering and severe performance degradation or process crashes.

    Note: Only applications that return a ReadableStream (or Response with a Web Stream body) via reply.send() are impacted

    Upgrade fastify to version 5.7.3 or higher.

    Denial of Service (DoS)

    fastify is an overhead web framework, for Node.js.

    Affected versions of this package are vulnerable to Denial of Service (DoS). A denial of service vulnerability exists in Fastify v2.14.1 and v3.0.0-rc.4 that allows A malicious user can trigger resource exhaustion (when the allErrors option is used) with specially crafted schemas.

    How to fix Denial of Service (DoS)?

    Upgrade fastify to version 2.15.1 or higher.

    <2.15.1

    Denial of Service (DoS)

    fastify is an overhead web framework, for Node.js.

    Affected versions of this package are vulnerable to Denial of Service (DoS). It uses allErrors: true by default which makes it susceptible to DoS attacks even when schemas are otherwise safe.

    How to fix Denial of Service (DoS)?

    Upgrade fastify to version 2.15.1, 3.0.0-rc.5 or higher.

    >=2.0.0 <2.15.1>=3.0.0-alpha.1 <3.0.0-rc.5
