CVE-2023-45825

Credential disclosure via error-message serialization

Published Oct 19, 2023 · Updated Sep 12, 2024

Sensitive data exposure in YDB Go SDK 3.48.6 through 3.53.2 allows local users to read custom credentials from logged connection errors. The balancer formats a custom Credentials object with %q in an error returned by ydb.Open, triggering reflection-based serialization when fmt.Stringer is absent. Exposure requires a connection failure, a token-bearing custom credentials object without String(), configured application logging, and access to the resulting log.
