Web Session Cookie Exposure Test via XSS

T1539 · MITRE ATT&CK

In an explicitly authorized staging application, validate whether same-origin JavaScript can access a non-sensitive synthetic session-cookie canary after an inert XSS proof of execution. This checks exposure relevant to MITRE ATT&CK T1539; it does not steal, transmit, or replay real session cookies. The test applies only to the configured canary and must not target production users or third-party sites.
