Name of the Vulnerable Software and Affected Versions IBM Langflow OSS versions 1.0.0 through 1.9.3

Description A Server-Side Request Forgery (SSRF) issue exists in the URL component located at src/lfx/src/lfx/components/data source/url.py. This is caused by a Time-of-Check/Time-of-Use (TOCTOU) race condition, which is a scenario where a system checks a condition (such as a security validation) and then uses the result, but the condition changes between the check and the use. This flaw can be exploited via DNS rebinding, a technique used to bypass Same-Origin Policy restrictions by changing the IP address associated with a domain name after the initial validation. This issue impacts data confidentiality in transit.

Recommendations Update IBM Langflow OSS to a version newer than 1.9.3.
