This makes these tokens much less random than they are expected to be, and so not cryptographically safe.\n\n### Resolution\nThe token generation logic used in the 2.0.x branch based on base64 encoding has been backported. This changes the range of characters used in the token. Any route placeholder expected to match a token generated by FOSUserBundle must be updated to allow dashes, which are not allowed by \\w in regexes. A \\w+ requirement should so become [\\w\\-]+.","public_affected_ranges":["ECOSYSTEM: introduced 1.0.0; fixed 1.3.5"]}],"null_published_at":"2026-10-31T22:12:48.025Z","source_updated_at":"2024-11-29T05:41:12.279Z","source_disclosed_at":"2024-05-15T21:42:25.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T21:42:30.992Z"}],"next_cursor":null,"snapshot_revision":"42594"}
