Link manipulation (reflected)
Summary: PortSwigger describes link manipulation as occurring when an application embeds user input into the path or domain of URLs that appear within its responses, letting an attacker construct a link that modifies the target of URLs in the response when another user visits it. The entry states the security impact depends largely on the nature of the application functionality, that the issue may have no direct impact but can be combined with other vulnerabilities to escalate severity, and that a whitelist restricting user input to safe values is a possible remediation.
What's compelling: PortSwigger notes that in some situations this issue will have no security impact and no remediation is necessary, so the decision of whether a reflected link-manipulation finding is real risk or noise rests on how your application uses that input.
