  "summary": "Guzzle OAuth Subscriber has insufficient nonce entropy",
  "details": "### Impact\n\nNonce 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.\n\n### Patches\n\nUpgrade to version 0.8.1 or higher.\n\n### Workarounds\n\nNo.\n\n### References\n\nIssue is similar to https://nvd.nist.gov/vuln/detail/CVE-2025-22376.\n",
