The flash.system.Security.exactSettings property should never be set to false

Vulnerability

BlockerSonarSource default severity
click to learn more

The Security.exactSettings value should remain set at the default value of true. Setting this value to false could make the SWF vulnerable to cross-domain attacks.

Noncompliant Code Example

Security.exactSettings = false;

Compliant Solution

Security.exactSettings = true;
