Cross-site Request Forgery (CSRF)

Abbreviations / Acronyms / Synonyms:

CSRF

Definitions:

  An attack in which a subscriber currently authenticated to an RP and connected through a secure session browses to an attacker’s website, causing the subscriber to unknowingly invoke unwanted actions at the RP. For example, if a bank website is vulnerable to a CSRF attack, it may be possible for a subscriber to unintentionally authorize a large money transfer, merely by viewing a malicious link in a webmail message while a connection to the bank is open in another browser window.
