NVD description
IBM Langflow OSS 1.0.0 through 1.11.1 is vulnerable to server-side request forgery (SSRF). This may allow an authenticated attacker to send unauthorized requests from the system, potentially leading to network enumeration or facilitating other attacks.
What to do
- Upgrade Langflow to
1.11.2or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
