Doc Text:
A flaw was found in Spring Framework. Due to incorrect host parsing in the UriComponentsBuilder component, applications that process externally provided URL strings may be vulnerable to a Server-Side Request Forgery (SSRF) attack. An SSRF attack allows an attacker to trick the server into making requests to an arbitrary domain, potentially leading to information disclosure or unauthorized actions.
