open-telemetry has an Observable Timing Discrepancy

OpenTelemetry, also known as OTel, is a vendor-neutral open source Observability framework for instrumenting, generating, collecting, and exporting telemetry data such as traces, metrics, and logs. The bearertokenauth extension's server authenticator performs a simple, non-constant time string comparison of the received & configured bearer tokens. This impacts anyone using the `bearertokenauth` server authenticator. Malicious clients with network access to the collector may perform a timing attack against a collector with this authenticator to guess the configured token, by iteratively sending tokens and comparing the response time. This would allow an attacker to introduce fabricated or bad data into the collector's telemetry pipeline. The observable timing vulnerability was fixed by using constant-time comparison in 0.107.0

OpenTelemetry 安全漏洞

OpenTelemetry是OpenTelemetry开源的一个供应商中立的开源可观测性框架。 OpenTelemetry 0.80.0版本至0.107.0之前版本存在安全漏洞，该漏洞源于具有收集器网络访问权限的恶意客户端可能会对具有该身份验证器的收集器执行定时攻击，以猜测配置的令牌。
