Guzzle OAuth Subscriber has insufficient nonce entropy

Check your stack

The advisory, in context

Impact

Nonce generation does not use sufficient entropy nor a cryptographically secure pseudorandom source (https://github.com/guzzle/oauth-subscriber/blob/0.8.0/src/Oauth1.php#L192). This can leave servers vulnerable to replay attacks when TLS is not used.

Patches

Upgrade to version 0.8.1 or higher.

Workarounds

No.
