The CSRF (Cross-Site Request Forger) protection enforced by the `@fastify/csrf-protection` library, when combined with `@fastify/passport` in affected versions, can be bypassed by network and same-site attackers. `fastify/csrf-protection` implements the synchronizer token pattern (using plugins `@fastify/session` and `@fastify/secure-session`) by storing a random value used for CSRF token generation in the `_csrf` attribute of a user's session. The `@fastify/passport` library does not clear the session object upon authentication, preserving the `_csrf` attribute between pre-login and authenticated sessions. Consequently, CSRF tokens generated before authentication are still valid. Network and same-site attackers can thus obtain a CSRF token for their pre-session, fixate that pre-session in the victim's browser via cookie tossing, and then perform a CSRF attack after the victim authenticates. As a solution, newer versions of `@fastify/passport` include the configuration options: `clearSessionOnLogin (default: true)` and `clearSessionIgnoreFields (default: ['passport', 'session'])` to clear all the session attributes by default, preserving those explicitly defined in `clearSessionIgnoreFields`."}], "lastModified": "2023-05-03T14:42:00.337", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:fastify:passport:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "3F071BA9-FBA0-4860-9B99-9D48230422D2", "versionEndExcluding": "1.1.0"}, {"criteria": "cpe:2.3:a:fastify:passport:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "341AD078-D84A-45B6-876F-7FA286EECAAA", "versionEndExcluding": "2.3.0", "versionStartIncluding": "2.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
