    Guzzle OAuth Subscriber has insufficient nonce entropy

    CVE-2025-21617 · GHSA-237r-r8m4-4q88

    Issue
    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.

    Recommended action: Upgrade to 0.8.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
