GHSA-237R-R8M4-4Q88

Vulnerability from github – Published: 2025-01-06 19:23 – Updated: 2025-01-06 22:15
VLAI?
Summary
Guzzle OAuth Subscriber has insufficient nonce entropy
Details

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.
