GHSA-c995-4fw3-j39m: Langflow Vulnerable to Code Injection via the `/api/v1/validate/code` endpoint
Langflow versions prior to 1.3.0 are susceptible to code injection in the /api/v1/validate/code
endpoint. A remote and unauthenticated attacker can send crafted HTTP requests to execute arbitrary code.
Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
