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"}, {"lang": "es", "value": "OpenTelemetry, tambi\u00e9n conocido como OTel, es un framework de observabilidad de c\u00f3digo abierto, independiente del proveedor, para instrumentar, generar, recopilar y exportar datos de telemetr\u00eda, como seguimientos, m\u00e9tricas y registros.
