How to Fix CVE-2024-35220

To remediate this vulnerability, upgrade all affected @fastify/session dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@fastify/session fixed: 10.9.0 
npm install @fastify/session@10.9.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @fastify/session

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-35220, inspect your project dependencies using npm:

npm ls @fastify/session

Analyze the terminal output to locate any version of @fastify/session in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 10.9.0), your application is affected.

Note: The npm ls @fastify/session command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-613: Insufficient Session Expiration, where according to wasc, "insufficient session expiration is when a web site permits an attacker to reuse old session credentials or session ids for authorization.". In @fastify/session, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact When restoring the cookie from the session store, the `expires` field is overriden if the `maxAge` field was set. This means a cookie is never correctly detected as expired and thus expired sessions are not destroyed. ### Patches Updating to v10.9.0 will solve this. ### Workarounds None ### References Publicly reported at: https://github.com/fastify/session/issues/251
