Descriptions

Apache Maven will follow repositories that are defined in a dependency’s Project Object Model (pom) which may be surprising to some users, resulting in potential risk if a malicious actor takes over that repository or is able to insert themselves into a position to pretend to be that repository. Maven is changing the default behavior in 3.8.1+ to no longer follow http (non-SSL) repository references by default. More details available in the referenced urls. If you are currently using a repository manager to govern the repositories used by your builds, you are unaffected by the risks present in the legacy behavior, and are unaffected by this vulnerability and change to default behavior. See this link for more information about repository management: https://maven.apache.org/repository-management.html

Apache Maven seguirá los repositorios que se definen en el Project Object Model (pom) de una dependencia, lo que puede resultar sorprendente para algunos usuarios, resultando en un riesgo potencial si un actor malicioso se hace cargo de ese repositorio o es capaz de insertarse en una posición para fingir ser ese repositorio. Maven está cambiando el comportamiento predeterminado en versiones 3.8.1+ para que ya no siga las referencias del repositorio http (sin SSL) por defecto. Más detalles disponibles en las URL a las que se hace referencia. Si actualmente está utilizando un administrador de repositorios para controlar los repositorios usados por sus compilaciones, no está afectado por los riesgos presentes en el comportamiento heredado y no está afectado por esta vulnerabilidad y cambia al comportamiento predeterminado. Consulte este enlace para mayor información sobre la administración de repositorios: https://maven.apache.org/repository-management.html

A flaw was found in maven. Repositories that are defined in a dependency’s Project Object Model (pom), which may be unknown to users, are used by default resulting in potential risk if a malicious actor takes over that repository or is able to insert themselves into a position to pretend to be that repository. The highest threat from this vulnerability is to data confidentiality and integrity.

*Credits: Apache Maven would like to thank Jonathan Leitschuh for highlighting the need for this change.
