CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

The vulnerability allows a remote attacker to escalate privileges on the system.

The vulnerability exists due to the Content-Security-Policy that blocks in-line scripts could be bypassed using an object tag to execute JavaScript in the protected document. A remote attacker can use such behavior in conjunction with XSS vulnerability on the website to bypass CSP protection using object tag when script-src 'none' is specified.
