Descriptions

Envoy is a cloud-native high-performance proxy. In versions prior to 1.22.1 the OAuth filter would try to invoke the remaining filters in the chain after emitting a local response, which triggers an ASSERT() in newer versions and corrupts memory on earlier versions. continueDecoding() shouldn’t ever be called from filters after a local reply has been sent. Users are advised to upgrade. There are no known workarounds for this issue.

Envoy es un proxy de alto rendimiento nativo de la nube. En versiones anteriores a 1.22.1, el filtro OAuth intentaba invocar al resto de filtros de la cadena después de emitir una respuesta local, lo que desencadena un ASSERT() en las versiones más recientes y corrompe la memoria en las versiones anteriores. continueDecoding() no debería llamarse nunca desde los filtros después de enviar una respuesta local. Es recomendado a usuarios actualizar. No se presentan mitigaciones conocidas para este problema
