CVE-2026-50635 · LimeSurvey Password Reset Host Header Injection Discloses Reset Token

Diese Seite zeigt ausgewählte Angaben aus den Quellen. Die vollständige Beschreibung und betroffene Versionen finden Sie in den verlinkten Sicherheitshinweisen.
LimeSurvey constructs account password-reset links from the client-supplied HTTP Host header without validating it. The optional allowedHosts allowlist that would constrain this is undefined in the default (and documented) configuration, so LSHttpRequest::checkIsAllowedHost() results in no operation. A remote, unauthenticated attacker who submits a forgotten-password request for a known account (requiring only the target's username and email) with a spoofed Host header causes LimeSurvey to email that account a reset link whose hostname is attacker-controlled while embedding the genuine validation_key. When the recipient or an automated inbound mail-security link scanner dereferences the link, the valid reset token is disclosed to the attacker, who replays it against the legitimate host's newPassword endpoint to set a new password and take over the account.
