{"id":"CVE-2023-29019","state":"PUBLISHED","title":"Session fixation in fastify-passport","description":"@fastify/passport is a port of passport authentication library for the Fastify ecosystem. Applications using `@fastify/passport` in affected versions for user authentication, in combination with `@fastify/session` as the underlying session management mechanism, are vulnerable to session fixation attacks from network and same-site attackers. fastify applications rely on the `@fastify/passport` library for user authentication. 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 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. As 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. Users are advised to upgrade. There are no known workarounds for this vulnerability.\n","publishedAt":"2023-04-21T22:28:55.045Z","updatedAt":"2025-02-04T19:38:59.862Z","severity":{"score":8.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["fastify fastify-passport"],"affected":[{"vendor":"fastify","product":"fastify-passport","versions":[{"version":"< 1.1.0","status":"affected"},{"version":">= 2.0.0, < 2.3.0","status":"affected"}]}],"references":["https://github.com/fastify/fastify-passport/security/advisories/GHSA-4m3m-ppvx-xgw9","https://github.com/fastify/fastify-passport/commit/43c82c321db58ea3e375dd475de60befbfcf2a11","https://owasp.org/www-community/attacks/Session_fixation"],"weaknesses":["CWE-384"],"ingestedAt":"2026-10-29T20:05:52.290Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/29xxx/CVE-2023-29019.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-29019","state":"PUBLISHED","datePublished":"2023-04-21T22:28:55.045Z","dateUpdated":"2025-02-04T19:38:59.862Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-03-29T17:39:16.144Z"},"containers":{"cna":{"title":"Session fixation in fastify-passport","descriptions":[{"lang":"en","value":"@fastify/passport is a port of passport authentication library for the Fastify ecosystem.
