MITRE ATT&CK Enterprise TechniquesAI

T1059.007 JavaScript Execution
Adversaries may abuse various implementations of JavaScript for execution.
T1539 Steal Web Session Cookie Credential Access
An adversary may steal web application or service session cookies and use them to gain access to web applications or Internet services as an authenticated user without needing credentials.
Why these techniques?

The stored XSS vulnerability enables high-privilege users to inject unsanitized JavaScript into plugin settings, which executes in the browsers of other admins (e.g., via onclick or accesskey), facilitating JavaScript execution (T1059.007) and web session cookie theft (T1539).
