Details

Guzzle OAuth Subscriber has insufficient nonce entropy ### 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. ### References Issue is similar to https://nvd.nist.gov/vuln/detail/CVE-2025-22376.
