How to Fix CVE-2023-29019
To remediate this vulnerability, upgrade all affected @fastify/passport dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install @fastify/passport@1.1.0npm install @fastify/passport@2.3.0Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls @fastify/passportHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2023-29019, inspect your project dependencies using npm:
npm ls @fastify/passportAnalyze the terminal output to locate any version of @fastify/passport in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.0), your application is affected.
Note: The npm ls @fastify/passport 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-384: Session Fixation, where authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions. In @fastify/passport, 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.

The login and user validation are performed by the `authenticate` function. When executing this function, the `sessionId` is preserved between the pre-login and the authenticated session. Network and [same-site attackers](https://canitakeyoursubdomain.name/) can hijack the victim's session by tossing a valid `sessionId` cookie in the victim's browser and waiting for the victim to log in on the website.\n\n## Fix\nAs a solution, newer versions of `@fastify/passport` regenerate `sessionId` upon login, preventing the attacker-controlled pre-session cookie from being upgraded to an authenticated session.\n\n## Credits\n* Pedro Adão (@pedromigueladao), [Instituto Superior Técnico, University of Lisbon](https://tecnico.ulisboa.pt/)\n* Marco Squarcina (@lavish), [Security & Privacy Research Unit, TU Wien](https://secpriv.wien/)",
