Descriptions

Improper input validation in the Pulsar Function Worker allows a malicious authenticated user to execute arbitrary Java code on the Pulsar Function worker, outside of the sandboxes designated for running user-provided functions. This vulnerability also applies to the Pulsar Broker when it is configured with "functionsWorkerEnabled=true".

This issue affects Apache Pulsar versions from 2.4.0 to 2.10.5, from 2.11.0 to 2.11.3, from 3.0.0 to 3.0.2, from 3.1.0 to 3.1.2, and 3.2.0.

2.10 Pulsar Function Worker users should upgrade to at least 2.10.6.
2.11 Pulsar Function Worker users should upgrade to at least 2.11.4.
3.0 Pulsar Function Worker users should upgrade to at least 3.0.3.
3.1 Pulsar Function Worker users should upgrade to at least 3.1.3.
3.2 Pulsar Function Worker users should upgrade to at least 3.2.1.

Users operating versions prior to those listed above should upgrade to the aforementioned patched versions or newer versions.

La validación de entrada incorrecta en Pulsar Function Worker permite que un usuario autenticado malicioso ejecute código Java arbitrario en Pulsar Function Worker, fuera de los entornos limitados designados para ejecutar funciones proporcionadas por el usuario. Esta vulnerabilidad también se aplica al Pulsar Broker cuando está configurado con "functionsWorkerEnabled=true".
