6DescriptionGitHub Advisory
Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.0, this vulnerability allows remote attackers to bypass authentication on affected installations of FlowiseAI Flowise. Authentication is not required to exploit this vulnerability. The specific flaw exists within the resetPassword method of the AccountService class. There is no check performed to ensure that a password reset token has actually been generated for a user account. By default the value of the reset token stored in a users account is null, or an empty string if they've reset their password before. An attacker with knowledge of the user's email address can submit a request to the "/api/v1/account/reset-password" endpoint containing a null or empty string reset token value and reset that user's password to a value of their choosing. This vulnerability is fixed in 3.1.0.
AnalysisAI
Authentication bypass in FlowiseAI Flowise before 3.1.0 lets an unauthenticated remote attacker who knows a victim's email address take over their account by abusing the password reset flow. The resetPassword method of AccountService never verifies that a reset token was actually issued, and because the stored token defaults to null (or an empty string after a prior reset), submitting a null/empty token to /api/v1/account/reset-password sets an attacker-chosen password. Publicly available exploit code exists (ZDI-CAN-28762, SSVC exploitation:poc); it is not listed in CISA KEV and EPSS is low (0.15%, 35th percentile).
