A software vulnerability is a flaw or weakness in a computer program that can be exploited by attackers to gain unauthorized access or cause harm. These vulnerabilities can arise from coding errors, design oversights, or misconfigurations, making it easier for malicious users to compromise the system. When a software vulnerability is discovered, it is often addressed through updates or patches released by the software developer. Regularly updating software is crucial for maintaining security, as it helps protect against threats that exploit these vulnerabilities, ensuring the safety of data and systems for users and organizations alike.
