Forced login via unanchored JSON content-type match
Published Aug 29, 2026 · Updated Aug 29, 2026
CSRF bypass in Rodauth before 2.47.0 allows remote attackers to force victims into attacker-controlled accounts via cross-origin forms. The JSON feature's json_request_content_type_regexp lacks a start anchor, so content types containing application/json anywhere are treated as JSON and skip CSRF checks. Exploitation requires JSON enabled without an anchored override, non-JWT JSON requests, and a victim visiting an attacker-controlled site; session impact also depends on SameSite cookie policy.
