{"id":"GHSA-98j2-3j3p-fw2v","summary":"Session Middleware Token Injection Vulnerability","details":"A security vulnerability has been identified in the Fiber session middleware where a user can supply their own session_id value, leading to the creation of a session with that key.\n\n## Impact\nThe identified vulnerability is a session middleware issue in GoFiber versions 2 and above. This vulnerability allows users to supply their own session_id value, resulting in the creation of a session with that key. If a website relies on the mere presence of a session for security purposes, this can lead to significant security risks, including unauthorized access and session fixation attacks. All users utilizing GoFiber's session middleware in the affected versions are impacted.\n\n## Patches\nThe issue has been addressed in the latest patch. Users are strongly encouraged to upgrade to version 2.52.5 or higher to mitigate this vulnerability.\n\n## Workarounds\nUsers who are unable to upgrade immediately can apply the following workarounds to reduce the risk:\n\n1. **Validate Session IDs**: Implement additional validation to ensure session IDs are not supplied by the user and are securely generated by the server.\n2. **Session Management**: Regularly rotate session IDs and enforce strict session expiration policies.\n\n## References\nFor more information on session best practices:\n- [OWASP Session Management Cheat Sheet](https://cheatsheetseries.owasp.org/cheatsheets/Session_Management_Cheat_Sheet.html)\n\nUsers are encouraged to review these references and take immediate action to secure their applications.","aliases":["CVE-2024-38513","GO-2024-2959"],"modified":"2026-08-24T00:35:51.435776425Z","published":"2024-07-01T20:35:03Z","database_specific":{"github_reviewed_at":"2024-07-01T20:35:03Z","nvd_published_at":"2024-07-01T19:15:05Z","cwe_ids":["CWE-384"],"severity":"CRITICAL","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/gofiber/fiber/security/advisories/GHSA-98j2-3j3p-fw2v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-38513"},{"type":"WEB","url":"https://github.com/gofiber/fiber/commit/66a881441b27322a331f1b526cf1eb6b3358a4d8"},{"type":"WEB","url":"https://github.com/gofiber/fiber/commit/7926e5bf4da03e54f62d27d53229d35b264cba8e"},{"type":"PACKAGE","url":"https://github.com/gofiber/fiber"}],"affected":[{"package":{"name":"github.com/gofiber/fiber","ecosystem":"Go","purl":"pkg:golang/github.com/gofiber/fiber"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.52.5"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 2.52.4","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/07/GHSA-98j2-3j3p-fw2v/GHSA-98j2-3j3p-fw2v.json"}},{"package":{"name":"github.com/gofiber/fiber/v2","ecosystem":"Go","purl":"pkg:golang/github.com/gofiber/fiber/v2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.52.5"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 2.52.4","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/07/GHSA-98j2-3j3p-fw2v/GHSA-98j2-3j3p-fw2v.json"}},{"package":{"name":"github.com/gofiber/fiber/v2/middleware/session","ecosystem":"Go","purl":"pkg:golang/github.com/gofiber/fiber/v2/middleware/session"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.52.5"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 2.52.4","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/07/GHSA-98j2-3j3p-fw2v/GHSA-98j2-3j3p-fw2v.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H"}]}
