Exploitability
| CWE ID | Description |
|---|---|
| CWE-89 | The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. |

AI Powered Q&A
Can you explain this vulnerability to me?
IBM Langflow Desktop versions 1.6.0 through 1.8.4 are vulnerable to a stored cross-site scripting (XSS) attack. This means that an authenticated user can insert malicious JavaScript code into the web user interface. This embedded code can then alter the intended functionality of the application.
How can this vulnerability impact me? :
The vulnerability can lead to the disclosure of credentials within a trusted session. Because the malicious script runs in the context of the web UI, it can manipulate the application behavior and potentially steal sensitive information such as user credentials.
