{"id":"GHSA-8wx3-8m4x-g5h4","aliases":[],"title":"FOSUserBundle User Identity Validation Vulnerability","description":"Versions of FOSUserBundle prior to 1.2.1 have been found to be vulnerable to a security issue related to user identity validation. Specifically, user refreshing was performed using the primary key instead of the username, leading to a potential security risk if a user is allowed to change their username. The fix in version 1.2.1 addresses this issue by loading the user using the primary key during refreshing.","severity":"medium","score":null,"published":"2024-05-15T21:43:23.000Z","modified":"2026-07-16T18:45:48.271Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"friendsofsymfony/user-bundle","ranges":[{"events":[{"introduced":"1.0.0"},{"fixed":"1.2.1"}],"type":"ECOSYSTEM"}],"versions":["1.1.0","1.2.0"],"fixed":["1.2.1"]}],"references":["https://github.com/FriendsOfSymfony/FOSUserBundle/commit/1b8bc18e3d99ef0b52b4141f20da323033d6be9b","https://github.com/FriendsOfSymfony/FOSUserBundle/commit/5a36e2958068d1e6501dc8cf39bbae3ebb859d9f","https://github.com/FriendsOfPHP/security-advisories/blob/master/friendsofsymfony/user-bundle/2012-07-10-1.yaml","https://github.com/FriendsOfSymfony/FOSUserBundle","https://github.com/FriendsOfSymfony/FOSUserBundle/blob/master/Changelog.md"],"sources":[{"name":"OSV","id":"GHSA-8wx3-8m4x-g5h4","modified":"2026-07-16T18:45:48.271390210Z","url":"https://osv.dev/vulnerability/GHSA-8wx3-8m4x-g5h4"}],"assessments":[]}
