Spring Kafka's retry topic infrastructure did not sufficiently validate user-controlled header values before acting on them. A producer could send a record with a crafted retry_topic-attempts header to supply an out-of-range attempt count and cause the retry topic router to misidentify where the message was in the retry sequence.
Affected versions:
Spring for Apache Kafka 4.0.0 through 4.0.5; 3.3.0 through 3.3.15; 3.2.0 through 3.2.13; 2.9.0 through 2.9.13; 2.8.0 through 2.8.11.

Title: Spring for Apache Kafka de Spring, Description: La infraestructura de temas de reintento de Spring Kafka no validaba suficientemente los valores de encabezado controlados por el usuario antes de actuar sobre ellos. Un productor podría enviar un registro con un encabezado retry_topic-attempts manipulado para proporcionar un recuento de intentos fuera de rango y hacer que el router del tema de reintento identifique erróneamente dónde estaba el mensaje en la secuencia de reintento.
Versiones afectadas:
Spring for Apache Kafka 4.0.0 hasta 4.0.5; 3.3.0 hasta 3.3.15; 3.2.0 hasta 3.2.13; 2.9.0 hasta 2.9.13; 2.8.0 hasta 2.8.11.
