CVE-2026-21697
No affected components available
axios4go is a Go HTTP client library. Prior to version 0.6.4, a race condition vulnerability exists in the shared HTTP client configuration. The global defaultClient is mutated during request execution without synchronization, directly modifying the shared http.Client's Transport, Timeout, and CheckRedirect properties. Impacted applications include that that use axios4go with concurrent requests (multiple goroutines, GetAsync, PostAsync, etc.), those where different requests use different proxy configurations, and those that handle sensitive data (authentication credentials, tokens, API keys). Version 0.6.4 fixes this issue.

Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
