Vulnerability Title
Potential URI resolution path traversal in the AWS SDK for PHP
Source: CVE Program / CVE List V5
Vulnerability Description
AWS SDK for PHP is the Amazon Web Services software development kit for PHP. Within the scope of requests to S3 object keys and/or prefixes containing a Unix double-dot, a URI path traversal is possible. The issue exists in the `buildEndpoint` method in the RestSerializer component of the AWS SDK for PHP v3 prior to 3.288.1. The `buildEndpoint` method relies on the Guzzle Psr7 UriResolver utility, which strips dot segments from the request path in accordance with RFC 3986. Under certain conditions, this could lead to an arbitrary object being accessed. This issue has been patched in version 3.288.1.
