How to Fix CVE-2023-45286

To remediate this vulnerability, upgrade all affected Github.com/go resty/resty/v2 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/go-resty/resty/v2 fixed: 2.11.0 
Upgrade github.com/go-resty/resty/v2 to 2.11.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/go-resty/resty/v2

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-45286, inspect your project dependencies for Github.com/go resty/resty/v2:

inspect dependencies for github.com/go-resty/resty/v2

Analyze the terminal output to locate any version of Github.com/go resty/resty/v2 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.11.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition'), where the product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently. In Github.com/go resty/resty/v2, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A race condition in go-resty can result in HTTP request body disclosure across requests. This condition can be triggered by calling sync.Pool.Put with the same *bytes.Buffer more than once, when request retries are enabled and a retry occurs. The call to sync.Pool.Get will then return a bytes.Buffer that hasn't had bytes.Buffer.Reset called on it. This dirty buffer will contain the HTTP request body from an unrelated request, and go-resty will append the current HTTP request body to it, sending two bodies in one request. The sync.Pool in question is defined at package level scope, so a completely unrelated server could receive the request body.
