time-of-check to time-of-use (toctou) vulnerabilities
Time-of-check to time-of-use (TOCTOU) vulnerabilities refer to a type of security flaw that occurs when a program or system incorrectly assumes that conditions will remain unchanged between the time a check is performed and the time a particular action is executed. This vulnerability can be exploited by attackers to manipulate variables or conditions between these two events, potentially leading to unauthorized access, data corruption, or other security breaches.
