Impact
IBM Langflow OSS 1.0.0 through 1.12.2 An authenticated flow author could write attacker-controlled file content into any directory writable by the service account, bypassing the platform's local file access isolation safeguard. Via a crafted on-disk index, the attacker could also read the contents of arbitrary files accessible to the service process — including configuration files, secrets, or database files stored under the application's data directory.
An attacker can exploit this over the network, with a regular user account, without any action by a user. If it succeeds: high risk of data being read, high risk of data or systems being changed.
