Insufficient nonce entropy

Low

GrahamCampbell published GHSA-237r-r8m4-4q88

Jan 6, 2025

Package

guzzlehttp/oauth-subscriber (Composer)

Affected versions

<0.8.1

Patched versions

0.8.1

Description

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.
