Langflow < 1.7.0 Account Takeover

Synopsis

Langflow < 1.7.0 Account Takeover

Description

According to its banner, the version of Langflow running on the remote host is prior to 1.7.0. It is, therefore, affected by an account takeover vulnerability. An overly permissive CORS configuration (allow_origins='*' with allow_credentials=True) combined with refresh tokens issued with SameSite=None allows a malicious webpage visited by an authenticated user to issue cross-origin requests, steal authentication tokens, and abuse the built-in code execution endpoint to achieve remote code execution and complete system compromise.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Langflow version 1.7.0 or later.
