Severity: Information
Summary#

Invicti identified that the nonce used remained same for subsequent responses.

Impact#

An attacker can carry out a successful Cross-site Scripting attack by using this nonce.

Remediation#

The application must generate a fresh value for the nonce-value directive at random and independently each time it transmits a policy. The value should be at least 128 bits long and should be generated using a cryptographically secure random number generator.
