I accidentally clicked on phishing link but did not enter details. Am I at risk? What should I do now?

As You have clicked on phishing link but did not enter details, you can -

• UNC paths (stealing hashed passwords - IE only)
  
• Injecting malicious extension (used for gaining persistence on the victim browser)
  
• Injecting malicious browser updates (again, for gaining persistence on the victim browser and code execution)
  
• Browser plugin vulnerabilities (i.e flash, silverlight, java - for code execution)
  
• Attacking the router (to redirect traffic, open ports etc)
  
• Attacking LAN systems (exploitation is difficult from the restrictions of browser networking, but port scanning is trivial)
  
• The same can be done on the local system
  

Cross-site Request Forgery against vulnerable sites Honestly, there are hundreds of possible things that can happen when you get phished, just by clicking the link. But in reality, the last 5-10 years have been great for the advancement of website/browser/system/equipment security and you probably don't have to worry about the majority of these. So take a deep breath, you are most likely fine
